I don't know about your country, but in Sweden you can choose where part of your investment money (I think 40%) gets allocated.
On top of that you can choose where 100% of your private pensions are allocated.
Also some EU pension funds are already in the process of divesting from US markets...
I mean, the US public markets is about 49% of the worlds market so it is not like there aren't other options. Divesting doesn't mean moving everything out and pension funds also invest in non-public markets.
