I guess my question would be, who is expected to work these low wage service jobs? 

Teens sure, but their availability is very limited. No one's available during school hours, they can't really do 8hr shifts, and since managers don't get paid well either, you'd need a teenager to run the store too. 

Or maybe if you have elderly people who've paid off all their housing expenses and just work for fun. But I doubt they're going to be working 40hrs, and they'll be much more picky regarding the working conditions since this isn't necessary for their ability to live, but is done just for fun. 

So I'm not sure who else can fill in the necessary roles to run these low wage low skill jobs, that don't allow you to afford living in the middle of an expensive city.

 The only other option would be commuting, but who is going to drive an hour to get paid $7.25 when you could find the some job in a middle of no where town.

See this is exactly the problem. Government artificially keeps supply low. Your problem literally wouldn't be a problem in a free market. Instead every policy in place is meant to restrict new housing supply AND prevent loss of home equity.

Honestly I would fucking love it if zero low wage jobs existed in NY or San Francisco. Let them have no fast food, no Starbucks. Nothing. Reap what you have sown
