Simple: they create value for the right people. Namely, politicians who get their donations, and a generation that, despite not having enough children to grow the economy organically, doesn't want to work any... er... wants to retire.

Thus, they invest in retirement and pension funds, who in turn invest the money in businesses to earn a return. Since that return must increase constantly, and organic growth is no longer possible, you have to pull shenanigans as a businessman to meet the requirements of the shareholders, lest they kick you out of the plane with a golden parachute.

So we let them do those shenanigans and the politicians don't do anything about it.
