> For two (real ballpark number here) about 1 in 10 Americans would actively be subject to a German style exit tax like this, concentrated among working adults.

I'm sure that a sizeable percentage of Americans own a significant amount of shares via 401k or whatever, but it feels surprising if 1 in 10 own more than 1% of a company, because all of those people holding shares as investments will be buying shares in companies with thousands or millions of other investors.

But maybe it's true - I just googled about the US has 340m people and 32.5m companies - so the majority of them must be small (population/number of companies). And while a lot of companies will be owned by the same people or just administrative divisions of a group of companies, most companies have multiple directors so maybe on average it does balance out to 1 in 10 owning a decent chunk of a company. It just feels like a surprising fact.

This site [1] has some interesting stats on size of businesses, although it's interesting that in 2019 these figures say there were less than 8m businesses, which disagrees with what google told me. Also says over half of US companies have 0-4 employees.

It's a surprising number, but a useful one for calibration. Most people assume that the number is closer to 1 in 100 or even 1 in 1000, but that's because they forget the vast, vast numbers of people who just quietly run their own operations in some form. You don't have to be Apple to make enough money to pay the bills on your own, or even reach the high net worth category.

It's worth noting that the numbers don't vary that much between the US and the EU, which actually weakens my claim that such a tax would be politically unpopular if introduced. About 1 in 20 Germans seem themselves to own enough of a business to fall under their own exit tax, checking just now, but I'm not familiar enough with DACH business practices to know if setting up an actual honest-to-goodness LLC for a one man operation is as common there as it is in the United States.
