Wall Street Journal made this nice graph on Saturday.
Forget "who bears," it's the totals here that are mind-boggling. In most countries, if you add up the "employer" and "employee" contributions, you get between 30 and 40%. So, if a worker produces 100 euros worth of output, 30-40 euros immediately go to the government. And there is an additional 20%+ VAT when the worker goes to buy something. So, right out of the gate, we have a 50-60% wedge between working and the fruits of labor. Income taxes, corporate taxes and property, excise, and other taxes are all on top of that! It's a wonder anyone in Europe bothers to work at all.
(I haven't looked in to the numbers, but I presume the European numbers include financing of their health systems, and the US number does not. Don't feel so cheeky.)
