Even the ACA damaged the ability of those to earn a living by putting in place that infamous twenty hour rule. That wasn't done to benefit working people, that was done to benefit certain types of employers but more it was done to distort unemployment numbers by artificially raising the number of people needed to do that same amount of work each week.
