Kind of an interesting idea. I wonder if it might be better applied to specific legislation. For instance, for every bill that passes, all the legislators that voted for it get a share that's tied to that bill. Anyone who voted against it gets a sort of anti-share.
Decades hence, an opinion poll is run on the popularity of the legislation. If the net approval rating is positive, the people who hold shares get paid, in proportion to the popularity of the bill. If it's underwater, the people holding anti-shares get paid.
One could even give a legislator proportionally more shares or more antishares in inverse proportion to their share of the vote. For instance, if you were Barbara Lee who voted against the bill that allowed the U.S. to fight the war in Afghanistan, she'd get the same payout if her vote was in line with future public opinion as the entire rest of the House together would get if allowing the war was popular by the same margin.
