But...but...if you want the extra income, you have to work for it.
Clearly some do, clearly some dont. Clearly some people will take the extra income, with the hardwork, regardless of the tax.
That's my point. The more you tax the higher paid, the less likely it is that someone will strive to earn higher incomes given the amount of effort involved! Take it to its exteme....if you were taxes at 100% on everything over 70k, nobody would bother to seek to earn 70,0001 as that (and every additional) euro would be taken from them.
