It’s going to be interesting to see how we would deal with international stock ownership once we are at war with previous partners. An example might be how stock ownership of Russian shares was dealt with in the west.
Because most public companies have been surviving wars just fine so far in history? I also didn’t say anything about US stocks specifically. I consider it irrational to only invest in one geographic region.
It is simply a historical fact that nothing preserved value over time better than broad stock ownership. Not gold. It mostly carries psychological value.
In general, looking at history, wealth stayed with the wealthy no matter what. Example study: http://blogs.wsj.com/economics/2016/05/19/the-wealthy-in-flo...
