The UK has been such a finance powerhouse for a long time because it ignores all the issues and foibles of the super wealthy customers it serves.

As soon as they start punishing them with taxes and rules they’ll just move. It would only work with a global alliance which would never happen. You’d end up with even more wealth moving to small specialized off shore jurisdictions.

I largely agree with what you mean, just not the way it was expressed.

I actually think something closer to name and shame, or setting better examples would work better. Trying to get Musk to emulate Carnegie setting up the libraries, Guggenheim and his art. Encourage and reward the behavior that sees the wealthy spending money to create great and lasting public institutions, rather than great and lasting private wealth.

All coupled with an insane inheritance tax without loopholes.
