A ceiling on net worth for representatives is certainly an interesting concept, but not really relevant to the conversation.

It gets hard to show a correlation with time in service to detachment from reality when one of the longest serving members is the most grounded, and many of the youngest and most recent members are absolutely insane.

Even Pelosi is pretty progressive relative to the rest of the Democratic representation, and certainly of Congress as a whole. (Very feint praise given the field). She is certainly out of touch, but she was that way when she was far younger as well.
