We can break it easily by not voting for the hereditary class. But that takes educating the idiot voters.
If I remember correctly, up thru about 1900 or at least the latter part of the 19th century the House had a majority of freshmen for every new Congress. (Outside the South, which tended to return Reps over and over.)
Today there’s, what, 95% re-election rate?
As you say, we could pitch every one of them out at the next election if we chose to. Which means as a people we’re getting exactly the government we deserve.
