It hasn't happened in the US and it isn't going to happen in the US because above all else, rich people favor the quality of life they're able to achieve in rich countries. Where are they gonna flee, the EU? Where taxes are already higher? Ireland you said? A tiny country with little in the way of American-style luxury amenities that has zero interest in allowing them to immigrate there?
The rich will stay just like they did back in the 50s when the highest marginal tax rate was 90%. It's time to make them pay their share for the benefits they gain from this country.
What part of "shell corporations are not the same thing as actual rich people moving to a place" is difficult for you to understand? Shell corporations existing outside the US in no way is the same thing as the rich fleeing the country.
