I have written about this before, and predicted that a U.S. Senator’s proposal for taxing unrealized gains (that’s what “mark-to-market” means) would never be adequately explained. After reading about his latest pronouncement on the subject, I still think that’s the case.
I’m not sure how his new proposal is all that different from the last one. The new proposal does at least concede that taxing unrealized gains on certain kinds of assets is just not going to work, hence the limitation of the proposed tax to “tradeable assets” (whatever that means).
