A congressional trust that any representative can pay into, that is only allowed to invest in wide US-based index funds (or it could build its own index fund) or US bonds, etc. Basically: Allow them to invest in the future of the country they’re managing. Don’t limit it to only politicians, either. Let everyone invest if they want.
ETFs should be fine, individual stocks not.
And even ETF purchases and sales should be declared a week in advance or sth.
I like the idea you’re going for but it’s not sufficient.
An improvement on my original idea then:
