0% is not a valid approximation of "0.3% per year" (the relative error is (0 - 0.3) ÷ 0 = ∞ or (0 - 0.3) ÷ 0.3 = 100%), and I note that this article is strangely silent on what fraction of the total wealth of the 3.06 million millionaires was owned by those 9500 millionaires who left in 02024. Given that the rest of the article is mostly talking about golden-passport schemes which I think typically cost about a million dollars, it would be unsurprising to find that the majority of millionaires don't have enough money to participate.

My take is that, despite the ersatz news headline "...study reveals", this is a propaganda piece tailored to promote a predetermined conclusion by selective reporting of only the evidence that supports that predetermined conclusion, just like the marketing piece from Henley it is criticizing.
