Wow, you make this too easy:
1. Canada has socialized medicine, but is not a socialist country. They're capitalists, like America - they just happen to have a health care system that everyone hates.
Many of the countries you listed utilize the Nordic Model - The Nordic model is underpinned by a free market capitalist economic system that features high degrees of private ownership. To pay for social programs, those who work are taxed heavily. Most of their tax rates are higher than the highest tax rates in the USA.
2. Sweden (Nordic Model) - I hope you enjoy 29.5% - 35% income tax
3. Denmark (Nordic Model) Tax rate of 45% that is expected to be 55.80% by the end of this quarter
4. Norway (Nordic Model) - 38.52% tax rate, and will be 39% by 2020
5. Switzerland is expected to be 40% tax rate by the end of this quarter
6. Finland (Nordic Model) - 51.60% tax by the end of this quarter
7. Australia is a capitalist nation, like the USA. One of their political parties is openly socialist, but theirs is a capitalist economy.
8. Netherlands - 36.65% to 51.75% tax
29% to 55% tax - ouch! That's painful!
