That's exactly the problem. Government officials gravitate toward the wealthy because of greed and the wealthy gravitate towards government for the same reason. It's a quid pro quo, and it shouldn't be a surprise.
It's not enough to say "government and big business shoudln't be in bed together", they already are and they have been for well over a century. Politicians stay in power by not challenging the wealthy elite who own institutions. The wealthy elite keep their profits and wealth growth by buying off politicians. We can say whatever we like but unless we elect politicians who are hell-bent on breaking up this sleazy hook-up between big business and government, then it will just keep happening.
