At what certain point, as the president has so famously said, have we made enough money.... available to so many for free?

"We’re not, we’re not trying to push financial reform because we begrudge success that’s fairly earned.
I mean, I do think at a certain point you’ve made enough money. 
But, you know, part of the American way is, you know, you can just keep on making it if you’re providing a good product or providing good service.
We don’t want people to stop, ah, fulfilling the core responsibilities of the financial system to help grow our economy."
