Moving to a $15/hr minimum wage isn't necessarily a win-win for society: Because low-wage workers get less work experience under a higher minimum-wage regime, they are less likely to transition to higher-wage jobs down the road.
"The key intellectual upshot is that, despite what some people want you to believe, the laws of economic gravity have not been suspended. You can’t impose costs on some without trade-offs for others. You can’t intervene in the market without unintended consequences. And here’s a haunting fact that seems to make sense: Raising the minimum wage will produce winners among job holders from all backgrounds, but it will disproportionately punish those with the lowest skills, who are least likely to be able to justify higher employment costs."
