Sure and that's fine for you and me, but it also is more cost on those who are likely making $15/hr and get a lot of their meals out and about - which means their cost just rose with their paycheck.

Remember, making food at home in a nice kitchen is a luxury.

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.

You can't live off of microwave noodles and instant rice. Cooking meals not only requires a way to heat food but ingredients which go bad quickly (eg time to go grocery shopping) and time to assemble and cook ingredients (dried beans are cheap but take 12 hours, instant beans still take 10 minutes or so). Then remember food has to be palatable, which is an additional challenge with kids.

I'm lucky that I'm in a place now where I can make nice food from relatively raw ingredients and much of that stems from my (relative) wealth.
