Yeah, same way they have it in Sweden, it's called "BankID" and only a few banks are allowed to issue that

Eighteenths amendment prohibited selling of alcoholic beverages nationwide. Would that be active today, would that stop you from buying beer?

Well, if you read closely, the 70 rate is cutting to the sum above the threshold value. So if your salary is X + Y + Z, where X, Y, and Z are, respectably, the lower, middle and the high threshold values, the taxes you pay is something like

(X * alpha) + (Y * beta) + (Z * gamma)

and only `gamma` is 0.7, `alpha` is something like 0.35 and I assume `beta` is something in between.

So those who pay 70 percent taxes are already maxed out on the lower contributions in corresponding income range.

Dammit this is so awesome!! I was just thinking of similar concept for my blog. I think I now, what I'm going to do this weekend :)
