Well this won’t kill fast food completely.
What it will do is -
(a) allow family-run businesses to flourish (esecially those with lots of kids), cuz then the money stays in the same household, doesn’t matter what the rate of pay is;
(b) encourage the development of labor-saving machines to do the prep & cooking. We’ve seen this before with other industries, it’s only a matter of time & incentive now.
In other words, some will profit well from this situation, while others (like Obama’s peeps, who are about to become unemployed) will suffer a lot.
Plus make the local “ma and pa” eateries successful.
