>Mark says that he didn't plan to build a global company and wants to connect the world and serve people and all of that, but he could do that right now. All the things that people don't like about Facebook, he could get flatout rid of it
The same way they pay them now, they just pay them a little less. The obvious consequence of getting rid of the things that make Facebook worse is that it is going to cost them some revenue. If nobody at Facebook is willing to accept that, then they should not pretend to have any other goal than to maximise profit in the first place.
How would they pay their employees?
