Anti corruption PACs with tight and unvariable definitions of corrupt behaviour especially when it comes to money.

Small donation style like that Bernie Sanders campaign for some PACs, but others should allow billionaire whales. The key is to make the PACs impervious to outside influence on the key mission to only fund politicians demonstrating honesty and integrity.

Do multiple PACs, so theres no one point of failure. When an Honesty and Integrity PAC is corrupted, shut it down or exit it, taking the people with integrity with you. Leave the corrupted behind.

Do this for decades, make donors aware its a long term project and to build their donations into their yearly budgets. This will need communitarian bridge builders, something US people do very well when they're given the support to. Have yearly AGMs, promote them and make them easy to access, and easy for donors to ask questions of the PAC, a bit like Superannuation industry funds are supposed to do 'on paper' in Australia.

Finally there might be enough patriotic Americans in positions of power again that they start looking after the country and not oligarchs, and hey, maybe stop undermining every flower of hope that sprouts in the rest of the world to.

I think the role of money in US society needs to change. And i'd love to see US citizens decide, on their own terms, to demote its importance; rather than the hammer of poverty brought on by increasing wealth inequality forcing the demotion.
