Well, I'm no economist myself. I would hope that the people who actually have a direct effect on these types of policies would do all the appropriate research. If the plan is as flawed as you say it is, I imagine it would be discarded rather quickly. And I don't imagine if it was that Mr. Jenner would be calling me back to say "hey, we looked at that plan and it's crap". I'm just a guy with an idea. The important thing to remember is that in the end, they are just higher paid guys who know other higher paid guys. Maybe one of them will run with it.

None have much good to say about real experience with such tax systems.
