Hah, I'm not from the US (I'm actually from one of those European nations you mention) and I see it from a different angle - the tax burden on higher income earners here is so enormous that people will find ways to work less to keep their earnings down, as the government just takes most of it. It has become a problem with doctors particularly - they will often opt to work fewer hours in order to earn less, as it simply isnt worth the extra time. This has made doctor access harder, which is a double disaster when you realise that the tax payer is the one who paid to train them in the first place. It is hard to argue that people paying tax in that bracket aren't doing enough already, and shouldn't be weary of any proposed increases in taxation.
