$15 ain't shit. I make more than that and I'm poor as fuck. Double that ain't shit in New York.
The minimum wage just makes it illegal to hire anyone below $15 an h our so that means a lot of unskilled workers won't get jobs. Without a minimum wage you can still demand a $15/hour salary, let's say at McDonald's. It's just that an employer will look at you and say, you ain't worth $15 an hour, maybe $5.50 an hour. $5.50 is not a lot, but it's better than being unemployed and getting $0. Now with the minimum wage at $15.00 I would say half the country would be unemployed.
