Fun fact, Ireland has one of the most unequal distributions of income in the EU pre transfers/taxation, and one of the most equal distributions of income after taxes and transfers.
So this stuff sortof works.
More generally, taxation of wealth is generally a good idea, but it needs to be over as many countries as possible to avoid people just moving.
You can accomplish most of the same goals by taxing property, as that's most of global wealth and it's harder to move.
You also need to handle the extreme top of the distribution through some kind of taxation on stocks/investments but property tax gets you most of the way there.
