I think it's more that the educated rich in Central London and Paris and Scandinavia are still secure in the instinctive knowledge that they own the country and the government, and that when government becomes smaller, the parts of it that they use will never be affected.
The "educated rich" in the US and Canada have no such sense of security?
Certainly less of it in the US than in Germany or Canada, and less of it there than in France or Britain. Yes, I would think so.
It's of course related to the filthy rich of the US being a much less homogeneous bloc - the Paris and London elites are
incredibly dominant. New York elites are under threat from, say, Dallas or Los Angeles elites with very different interests in a way that would be
quite unfathomable in Chelsea and Tunbridge Wells.
