The greater point is not that the buggy whip manufacturers are going to lose their jobs,
That analogy is adding insult to injury. Buggy whip manufacturers lost their jobs because no one was willing to buy their services. Losing your customers because you can't keep up with their evolving needs is on you. Losing your customers because the transaction was outlawed by a third party is not on you.
but that the net impact of 'some' job loss on overall earnings growth and mobility is immaterial - particularly on the bottom 25% of earners.
No. It's immaterial to
some members of the bottom 25% of earners. It's highly material to other members of the bottom 25% of earners. And it's especially material to the non-earners who are poorer than the bottom 25% of earners and would like an opportunity to move up in the world by becoming part of the bottom 25% of earners.
It is clear from the study that increasing the minimum wage is a net positive to society
Who is "society"? When one and the same policy is a negative for some members of society and a positive for different members of society, who is in charge of defining whether the harm to some is outweighed by the benefit to others? Do you have some objective measurement of outweighing in mind? Or by "It is clear from the study", are you merely expressing a subjective feeling that you care more about what was done to the beneficiaries than about what was done to the victims?
and particularly the poorest in society. Is anyone going to address that
Been there, done that. You are wrong. The study says jack all about whether it's a net positive particularly to the poorest in society. There are two reasons its methods are intrinsically unable to address that issue at all. First, the results it's reporting are statistics
about aggregates. The authors calculate that the Nth percentile collectively got X more money because of a minimum wage hike. That necessarily lumps together people who got Y less money with different people who got X+Y more money, for a net gain of X. It does not and cannot provide a reason to think "the poorest in society" are in the "X+Y more" subset rather than the "Y less" subset.
And second, as I noted earlier, the authors excluded from their analysis both first-time job seekers and people who lost their jobs because of the minimum wage hike and were never able to get new jobs. The study does not and cannot provide a reason to think "the poorest in society" are not in either of those groups, because it didn't look at them.
(The authors didn't give a reason for the exclusion; but presumably they excluded first-time job seekers because they weren't in the database at all, and excluded permanent job-losers because their database couldn't distinguish them from those who died, or became disabled, or left the country, or became stay-at-home moms, or...)
or are we just going to pick at straw?
Is "straw" what you call pointing out that the specific claims people have made about the study are false?
What the study provides is prima facie evidence that minimum wage hikes in the time period studied usually delivered more money to their beneficiaries than they stripped from their victims. If that had been what Alternet and CC said it showed, I wouldn't be picking. You got a problem with that?
