I have to ask, did you say the thing at the time the supposed exodus was getting lots of media coverage? I expressed skepticism about it at the time, although I did not pay it too much attention because I don't live int he UK. But any skepticism about such a prediction always incurs a bunch of people insisting I don't understand economics and explanation of how freely the wealthy can flee a high tax jurisdiction.

I notice you don't identify any particular investigative shortcomings or fallacies in the report; you just think it's absurd to even consider the viewpoint of an organization that argues the wealthy are undertaxed.

I'm also interested in how they've come up with the 3 million millionaires in the UK figure, they only seem to cite themselves for the data.

4.5% of the entire country are millionaires? On paper or in home equity + pension maybe... But those aren't the people we're concerned about leaving.

The article is basically worthless. Wealth follows a power law; saying 90x% of millionaires didn’t move is noise. The very wealthy are in fact moving; they don’t want to be subject to a tax jurisdiction that claims reach on global income. Now, they weren’t paying tax on that income before, so it’s not like it will make a huge impact on UK revenues, but I know that those folks tend to hire local professional services, bankers, etc; we’ll see if they keep doing business with the UK or look elsewhere, like the US. Smart money would be on the US + Dubai right now I think.
