I think you have this backwards, paying others to make food for you is a luxury. If you can afford a $50 microwave that you can then use to make meals that cost less than a dollar, that is the standard. You don't need a 'nice kitchen' to eat at home. Not to mention, their wage is double the $7.25 national minimum wage, but food prices at these restaurants do not double in response, so they still come out ahead.
