Yes, I think there are. There are actions that would certainly help to at least make public policy neutral. I talked about one of those in answering Judy's question.
I really am worried about a system that jerks the valuation all over the place. Any prudent corporation doesn't want to have his earnings jerked all around by assumptions that accountants force him to make about an interest rate to value liabilities, for example.
So I think there are clear things that can be done. Exactly how to do them is a much more difficult question, however.
