Earlier quoted context omitted.
Their tax rates are only a few percentage points different from ours. I think the difference is that we funnel 20% of it to the military (2% for Norway) and their tax code probably has fewer loopholes for the rich to exploit.
Their total tax burdens are much higher than US citizens' tax burdens unless you're making 7 figures of W-2 income. The top marginal tax rate kicks in an order of magnitude lower in those countries, and hits most of the middle class. In the US, it hits very few people. Also, the military is 20% of the discretionary budget, but 10% or less of the total budget.
The argument that other countries might be technically higher in taxes will remain moot so long as in the US, needing an ambulance could mean years of financial hardship if you're not sufficiently well off. The same goes for lodging, food safety, etc.
