Offering socializing and games to keep low-paid workers is simply dishonest psychological manipulation, because people cannot use these not monetary awards to pay their bills. For low income people, ability to pay bills is more important than satisfaction from games. Employees need to be paid more for better productivity. When it comes to non-monetary rewards, simple basic fairness is all what is needed. This is what I practiced when once I was put in charge of a deeply dysfunctional company with about 300 people working there. It worked well.
