Actually, the study found something that should interest liberals greatly. Though, it hasn't even been peer reviewed yet.
So the study concludes that the rise in the minimum wage ended up creating more higher wage jobs.
This is good news objectively, but does little to help low-skilled workers $15 minimums are supposed to help. (I'm agnostic on the matter personally. Think it's a wash either way)
It is not peer reviewed & I don't why it should even be discussed. Forget the good aspects,non-peer reviewed studies are largely considered junk in the academic world! This isn't credible by any standards !
Edit - Also unsurprisingly WaPo posts this. Jeff Bezos who owns Amazon has a huge share of minimum wage workers in warehouses & what not. What a clear conflict of interest in pushing through a non-peer reviewed study as a "Very Credible new" study !
