Taxes can be an effective tool, but they have to make sense. You can't kill a businesses ability to compete, nor can you remove the incentives to build wealth.

I could easily see any nation trying to implement higher taxes on the rich to also implement a wealth export tax that takes a tremendous portion of their accumulated wealth if they try to jump ship and take it overseas.
> not bringing it to the high-tax country in the first place.
This is the larger concern, but if a society can't survive without the good graces of the lucky rich, it is already their slaves.
Or they can penalize countries who operate tax havens - it's not like tax havens represents a significant amount of either trade or GDP.
Practically speaking, ya, it would be a challenge to make the system fair. But either the rich will pay, or there will eventually be some kind of destructive revolution to bring things back into balance (probably by making everyone poorer).
In many cases wealth isn't liquid. Wealth exists in the form of securities and assets. If you were to attempt to tax these, there would be absolute chaos - bank runs, stock market crashes, etc..., as everyone tries to liquefy their assets or move to protect them.
You could potentially tax cash savings, but that's not going to change much.
We saw in France a huge uproar over the threat of a 75% tax, thankfully the courts declared it illegal...
