Maybe, but America has relatively low taxes and high income.
This is an anecdote, but I was looking at developer jobs in Europe and the salaries are pathetic. 65k Euros for a senior engineer with a 50% tax rate? Are you fucking kidding me? I can make 250k in the US at a 35% rate. It’s absurd.
Do keep in mind that Europe is not a single country. Within the European Union, salaries and tax rates vary greatly. For western Europe, that seems a bit low.
Besides the northern countries, the tax rate is not 50%. Most countries either have a flat rate that is well below that or have a system where you pay in boxes. Like %30 over the first 20k, then %47 over the remainder etc. On top of that, many countries have countless schemes that result in tax deductions. Like owning a house gets you a discount.
In almost all cases, the effective tax rate falls well below 50%.
This is an 11-year old article and honestly total bullshit. European developers and professionals in general are quite happy with the welfare in Europe. It's a completely different mindset. Yes we earn much less, but at least if we can sick or fired we know we can get some decent support from the state.
