Well... It's not sustainable for the person making $15 an hour, but it's certainly is for the person paying that person $15 an hour and I think that those are the only people that we should be caring about.
Listen you got to work 6 days a week and go to church on Sundays. That's how it's supposed to work. That extra 20-30 bucks you get at the end of the month, collection plate.
Then you can die quietly at 55 and somebody can take your place.
/S obviously.
