I'm concerned about the use of sanctions, and the individual targeting of wealthy individuals as being anathema to the Rule of Law, property rights, and free exchange.
The dollar is inflating at the same time the reserve currency status is threatened, and we Americans, via our allies, are appropriating the stuff of foreigners, seizing boats, currency, gold, and property. I think >400B has been seized at this point.
How long until we move from "Russia Bad!" to other groups, and start turning inward onto ourselves, seizing their property because they are politically unpopular?
