Argentina seized pensions a couple years ago, no? And Team Obama seized the value from GM bond holders, yes? And the “conservative” Supreme Court OK’ed the Kelo decision, no? State of CA seizes the contents of bank safety deposit boxes after some ridiculously short period of no access, yes? Seizing appears to be an approved meme among govt folk. And it has precedent, FDR seized private gold.
An elder relative, a wise man, has been telling me for years to avoid govt constrained pension plans (401K, IRA, etc). He says “take the tax hit up front, put it in real property, preferably out of the country.” I.e., US Feds probably won’t seize your foreign acreage. Just hold it, and sell when you need the cash, with no silly age requirements.
