The the hell would anyone want to work for $3 an hour for twice the hours? That's goddamn insanity. 

I believe minimum wage should be enough for a person to sustain themselves above poverty levels. Considering how fucking hard it can be working in retail and other similar entry-level jobs, I do not believe most workers are compensated fairly for the work they put in.

I'm not saying somebody who stocks shelves for a living should be paid like atradesman, but they should be able to afford rent, groceries, and be able to have enough left over for savings without living in constant worry that a single unexpected expense is going to force them to choose between eating and having a roof over their head.
