There are two fundamental problems with UBI:
1) The numbers don't work. Eventually that will change.
The numbers do work. Total productivity is far more than adequate to feed, house, and clothe everybody; The reason people are hungry, ragged, or homeless is that the fruits of that productivity are unequally distributed.
The fruits are also unequally
produced.
I'm all for making massive changes to corporate tax laws, as well as strengthening and simplifying our assistance programs. But I am quite strongly opposed to this notion that everything should be equally distributed, or that everyone's survival needs should be seen to (by someone else) just because they got born.
Being born doesn't entitle you to the fruit of someone else's labor.
2) It's a trap. If society takes a downturn and can't afford UBI you will have a whole bunch of people with no useful job skills. Putting them back to work would be a slow process.
On the contrary, under the current system there are a whole bunch of people who have neither the time nor the money to obtain useful job skills.
Bullshit. I mean, entirely absolutely bullshit. Skilled trades are in high demand, pay quite well, are needed everywhere. And most high schools in the US (not all, of course) have some sort of VoTech arrangement. Enrolling in trade schools is waaaaaayyyyyy less expensive than university or even community college, and they almost all have apprenticeship programs once past the basics, so you get paid as you continue to learn.
There is a constant need for medical billing specialists. Many hospitals will teach the needed skills, and many community colleges offer one-year course for the basics. Heck, most insurance companies will hire entire classes of people for customer service jobs, and pay them while they're in training to learn how to do the job.
FFS janitorial positions pay pretty well, and there's no special skills involved.
Under a UBI, more people would have the time and money for education; And likely more people would want to be employed, as working conditions would need to improve very sharply. Nobody would work for an abusive boss, knowing that quitting wouldn't be a complete disaster for them financially, so bosses would need to make working much more attractive and pleasant, with shorter and/or more flexible hours, more collaborative decision making, and (for those jobs that cannot be made pleasant or enjoyable to do) higher wages.
There would be a massive shift in the kinds of employment that would be low paid vs high paid; And a huge shift in attitudes towards work by employees, and towards workers, by employers.
So in your opinion, this approach of giving everyone free money is somehow going to change the entire nature of the human psyche? It's going to make all the meanies into nice people and all the jobs into high-paying gigs, and everyone will want to work and nobody will be lazy or opportunistic, and basically it'll just fix the entire human race.
