Actually, in Norway there is some outrage. Many people with (a lot of) money move to Switzerland. There is also the issue that startups are being taxed on "paper money" — the value of the firm on paper based on expected future income — even though they have not yet started earning money.
From what I can find, the top wealth tax rate in Norway is about 1.1%. That seems pretty dumb to leave your home country to avoid paying 1.1% tax per year. For entrepreneurs that now have enormous equity (100s of millions of Euros), my sympathy is low. They can easy sell a tiny fraction of their equity to investors to pay the wealth tax.
Europe definitely needs to find replacements for the USA as a trusted partner. The US now supports Russia in its war against Ukraine, imposes random tariffs, pressures European companies over DEI (I'm not particularly woke myself, but I think equal opportunities regardless of race, for example, is a good idea), and makes threats against Greenland, Canada and Iceland. It also puts pressure on free speech and EU digital rules: the US imposed visa bans on former EU Commissioner Thierry Breton, an architect of the Digital Services Act, and four anti-disinformation activists, and I believe it also had his Microsoft email disabled. Add to that climate denial, the war on science, threats to leave NATO, antivax etc. I believe many countries will unfortunately turn to China, since even China is more predictable than the US.
