That's the rub, of course. I suspect there's a whole array of valid measures sufficient to blunt incentives. We don't need something perfect, just enough so legislators don't gain so much that their pecuniary motivations override their duty to public service (and their fear of getting caught). Right now they can profit massively from legislation by betting on individual companies. If they're instead looking at a blind trust that contains a mix of index funds, bond funds, etc, then they still are aligned with the wealthy, which is certainly bad, but any gains they can drive for themselves become much smaller.
