In some countries, certainly the UK in the 1960s with its 90% top tax rate, the government would've collected more tax if the rate were lower because there would have been more economic activity to tax -- or so say a lot of economists. "Laffer curve" is a good thing to search for if you want to learn more.

I mean, this is largely to my point, though? Last I looked, it seemed research into the Laffer Curve largely found most countries set their rates below the ideal. Agreed that a 90% rate would almost certainly be too high, but the general feel was 40-60 would certainly cover the maximum rates. Some folks saying as high as 70, no?
