Americans on HN acting like they have an ownership stake in what their ruling class owns is as much a classic as Europeans coping with having no efficient capital markets.
To be fair many of them do have at least a small ownership stake in what their ruling class owns, since their pensions are invested in the public markets as well as, to a more limited extent, VC and PE through various funds and stakes held by public companies.
Euro pensions are also invested in the American stock exchange... Ownership in global markets is a complicated thing, no doubt the US is both significantly richer, and has a lot more levers to pull. But if things really go down hill (eg. the trans-atlantic relationship breaks down), I doubt the bottom 95% in the US will be better off than the bottom 95% in Europe.
