Most (if not all) of these cases are not dealing with tax evasion. It's actually legal tax avoidance, so there's no way to seize the assets because no-one has actually broken the law.

Many countries have very low (or zero) tax rates, so you can legally set up a company and put your money there.

I think one way to get rid of tax havens is with an international treaty to set some minimum tax rates, and have an embargo against any country that doesn't meet those requirements. It's not just the rich who are to blame, it's the countries that turn themselves into tax havens and make this all possible.

The laws say whatever politicians want them to say. If you pay the people who write the laws to turn your tax evasion into a legalized form of "tax avoidance," the inverse can just as easily be done to turn "tax avoidance" back into "tax evasion."
