I'll rephrase the above comments: having seven figures of assets or income confers material wealth but not political control. Political capital is far more expensive. At a minimum, you need so much money that hiring a team of lobbyists to confuse your local congresscritter is a petty cash drawer expense. Ideally you will also want to forefeit your right to privacy and become some kind of a public figure.

A case study here would be Louis Rossman: rich enough to run a MacBook repair business but not rich enough to bribe/tip Congress into passing a right-to-repair law.
