"arguably, better pay does more good than harm" = Leftist doctrine disproved by real-world fact.
But
Minimum Wage is popular with the mindless masses, so nevermind the real world. Just preach the Leftist slogans they want to hear.
There are good reasons for a state imposed minimum wage.
But overall there's more harm than benefit from it.
How do you know? . . . Your objections are unfounded.
. . .
Sure, profits may decrease for some, but . . .
That's not all that decreases. It's also production and jobs which decrease, as higher costs are imposed onto employers.
. . . but that is not harmful to the workers who . . .
It's harmful to all the workers who lose their jobs or can't get hired in the future, and to all the consumers, because it increases the cost of production = higher prices. It harms all those workers (who are consumers) by increasing the prices they have to pay. Of course some of the particular workers who get higher wages might benefit, if their higher wage is higher than the higher prices they pay, but every minimum wage increase means reduced production and fewer jobs because of the higher labor cost, and higher prices for all.
There is no way to calculate exactly the reduced production and higher prices. But these are inevitable, in some amount. If you think not, then explain what happens if the minimum wage is doubled, from $15 to $30/hour, or to $40/hour, or to $50/hour. You have to admit that it causes job loss and higher prices, and probably shortages to all consumers, as companies shut down production rather than pay such high labor cost. You have to be a fool not to understand this. Never can the MW be increased that much because of the obvious damage it would inflict. So then, what if instead it's increased to only $25 rather than $30/hour? or to $20/hour? There's no evidence of any abrupt cutoff point where the damage suddenly happens at wage levels from that point or higher, but not below that point. Rather, as the labor cost or MW is increased slowly above the market-clearing level -- up from $10/hour, up from $12, from $14, from $16 etc., to higher and higher levels -- the damage done keeps increasing, more and more, as the production is reduced and prices are increased.
There is no empirical evidence to show how much damage is inflicted, but there has to be damage to the economy if higher costs are imposed onto the production, because otherwise the wage level could be driven up without limit with no harm to anyone other than the greedy capitalists, which is not the case. It hurts everyone else also.
The best wage level to get the best results is whatever level is necessary to attract the needed workers, so that the work gets done, and every single worker chooses what wage level is satisfactory, at which it's high enough to be worth it to that individual worker. He/she refuses to do it below that level -- a free choice, meaning it's in that worker's interest to have that job rather than not have it (at that wage level). This level is also the maximum level of production possible, which is always in the consumers' interest. Higher than this level means employers reduce the production (cost too high), whereas below this level means enough workers cannot be found to do the needed work (pay is too low).
So the optimum production-pay-cost level is that which the worker accepts as high enough to make it more worth it to do that job than to not do it, but as low as possible to keep the cost down to attract more buyers.
This is the best wage level for all workers who want to keep their job and are consumers and have to pay prices.
. . . not harmful to the workers who enjoy a better standard of living and spread their . . .
But that's only those particular workers who get the increase, but not any others who get no increase, including all independent contractors, and some wage-earners already above MW. And as the MW is spread more widely it also spreads the higher prices more widely to consumers. You can't increase it or spread it to more wage-earners without also driving up prices higher to pay for it. The higher costs and prices are imposed onto ALL consumers, all workers and all non-workers, while the benefits to some workers go to only those getting that wage increase.
In addition the new unemployment caused affects more workers as the higher wage level is increased, and this too cannot be exactly measured, but every minimum wage increase pushes up unemployment more and more, as hiring by employers is more and more discouraged by the higher labor cost.
. . . not harmful to the workers who . . . spread their disposable income throughout their community, shops, . . .
No, there's no additional income spreading, after you factor in the reduction of disposable income of those who have to pay for the wage increase (which must be paid for). Those who have to pay for it have LESS disposable income to spend -- i.e., the increased disposable income for some wage-earners is offset by the decreased disposable income of others elsewhere who have to pay for it.
You can't just wave your higher-wages magic wand and give widespread income increases to select beneficiaries without imposing cost onto others who have to pay for it.
. . . throughout their community, shops, cafes and service providers benefit (which includes businesses who employ workers) . . .
No, all of them have to curtail some production as a result of the higher labor cost. Plus, the higher prices ALL consumers must now pay results in lower demand from consumers generally, offsetting any increased demand from some who got pay increases as workers. You can't increase the total demand by giving more money to some which has to be paid by others, because the latter are also consumers, and their incomes are reduced by the higher labor cost.
. . . so, arguably, better pay does more good than harm.
So, if we double everyone's wages that produces more good than harm? No, it's undeniable that a high degree of increase must do more harm than good. So, at what lower point can you be sure that the good outweighs the harm? We know of no case where it did more good than harm to force up the wage level.
Both theory and practice prove that it can't be done. In the one case of Samoa where the wage increase was significant enough so the result was measurable, it caused reduced production and job losses which were so bad that those who enacted the wage increase had to rescind it, so everyone recognized that it did more harm than good. But there is no case showing the opposite result of more good than harm caused by a MW increase. No one believes a MW increase ever benefited society except Leftists and labor union ideologues and certain workers who got an increase (and their sympathetic friends). But even the Leftist ideologues and pro-labor politicians who imposed the MW increase in Samoa had to recognize that it did net harm to Samoa.
There has to be a standard recognized by all for judging whether it worked or not. When the law imposing the higher wage had to be rescinded even by the ideologues who enacted it, that proves it did more harm than good. When all sides recognize the result, then it's proved objectively.
But you can't name any case ever where both sides agreed that it did more good than harm.
But use your common sense. Consider low-paid workers, like immigrants seeking entry to the U.S. Here's a case of an immigrant from Ghana working full-time in Tijuana, earning $100 per week.

His employer is not a super-rich capitalist who can afford to pay all his workers $15/hour as you demand every worker in the world has to be paid (or $5 or $10 c.o.l. adjusted). If you impose your demands on all workers everywhere, it would shut down probably 20 or 30% of the world economy and cause mass starvation, not "a better standard of living" enjoyed by workers who "spread their disposable income throughout their community" when businesses have to shut down and low-paying jobs are eliminated and production decreases. These bad conditions are the real results, in the real world, such as happened in Samoa when your plan was imposed onto society. By ideologues who finally had to admit that the real world does not produce the utopian results your Progressive economics doctrines promise.
Your theories to "spread their disposable income throughout the community" have nothing to do with the real world of supply-and-demand and tough choices and competition and cost-control. Go tell those theories to this immigrant from Ghana, to his fish-market employer in Tijuana -- tell them how everyone will be made prosperous if that shop increases their wage to $5 or $10 or $15/hour and how this would "spread" the income around to all and raise everyone's living standard.
