Seems to be evolving slowly, though, i have some suggestions:
1. Make game items more expensive and prostitution a more attractive option
Since the in-game money gets almost like useless after about 2 hours of gameplay, i suggest making in-game work less valuable (this counts to prostitution too) so players struggle a little more to make money.
2. Alternative Game Overs (Starve to death, get killed...)
This way the game becomes more immersive and realistic overall, since you'll have to get money to buy your own food and be more careful about what you do/where you go.
3. If someone beats you up too hard, the game blinks a white screen and you wake up at the hospital
