But should a 27 year-old fry cook make enough money to live alone? Labor is labor. Pay shouldn’t be less because it’s going to an acceptable to abuse class of person.
Having roommates in a 1 bedroom apartment is quite terrible. You then need to convert (if there even is one) the living room to a second bedroom and as a result no one in the apartment has any privacy left. I have lived like that, and it's just not great for mental health.
Roommates in a bigger apartment or house is quite reasonable. 1-bedroom apartments are more than half the price of 2-bedroom apartments, so some efficiencies can be had by sharing a kitchen.
