Regulatory capture only works if we vote in people who let them do it. It’s not a much different issue to enforcement of rules that stop companies from getting too big or shut them down. The same thing that does or doesn’t let regulatory capture happen also stands in the way of any other government attempt to control the companies.

I've noticed that regulatory capture by lobbies generally happens as a long-term process. Public opinion quickly gets tired/bored of a specific issue, while lobbyists never stop pushing.

On the other hand, a politician that makes one of his/her main goals to shut down (or block if not in US) the GAFAMs (or any other giant company), might be actually able to make a real and long-lasting change.

(Or the other way, to change a few of the most important laws that describe how ALL companies can function – also could be a main policy point.)
