I had a government job where my boss arranged for his staff to be very well paid per hour of work. I can be pretty sure that he would not have been quite as generous if it had been a private partnership and our pay had come out his partnership share of earnings. He might have paid us as much, but he would have granted us less vacation time than the government organization granted us and we would have had to work with greater intensity.
This observation does not mean anything negative about anyone, it is just an observation on human nature and incentives. It is so much easier to be generous with someone else's money, particularly when they are taxpayers or rich people.
