What if -- bear with me here -- the very thing that makes those founders able to make the $1B they would otherwise make would drive them to also ask why it is that someone else who had no hand in building or funding it gets lion's share of the $900M while they get only $100M?

You don't /know/ that people need to collectively get over "this" -- you have a feeling that it seems more fair to do that than the alternative. But you can look at what happens elsewhere in the world with regimes that implement exactly what you are describing. And what happens is the people who are most equipped to be the golden gooses that you are proposing are just as equipped to simply most somewhere they can do so unencumbered.

That's why what you're proposing will just never really work.
