You could cut the salaries of those legislators or POTUS to $0 and it wouldn't matter. That's not where they make their money.
The Clintons and Obama's never held a job that pays more than $500k/year, but they are worth tens or hundreds of millions. Way more than they ever earned.
Same with most of the congress critters.
They all view the positions as a license to steal, insider trade, extort, and just plain print money.
