Oh really? What is that power? The power to get govt to things on their behalf? There's your problemNo. That's one of the problems (others: cartels, influencing public opinion with your media, having people or ideas killed, using his money to buy influence with people, etc).
And you seem naive enough to think that somehow we could do with him not getting govt to do things on his behalf.
Maybe by reducing or eliminating the government? This is a sure-fire, tested way to have the rich guy and his friends have a free reign to anything with no stop gaps.
You seem to see it:
(1) government = some people with power, that they abuse or rich people can buy them.
It would help to also see it this way:
(2) government = the ONLY power that is elected and somewhat controlled by the general public and its will.
