I don't think that's the case. $530 is nearly 10% the median household income. And that's just healthcare. Keep in mind countries with higher tax rates aren't just getting socialized medicine but vacation days, parental leave, cheaper education, and usable public transit.
Germany's system is generally liked, and "the public option" is ~15% of income (but we "split" it between employer and employee so it doesn't look as grim, which means you get half of that less in salary, but only pay half yourself).
10% seems reasonable, and is something you'd only achieve in Germany if you have a high income (because the total amount paid is limited) or go for private plans (which you can if you're self-employed or in some special cases, or if you have a high income; caveats apply). The public insurances also provide a much lower level of service than the private entities (e.g. you're paying for glasses yourself unless you're basically unable to function without them).
That's on top of having income tax on the higher side and a high VAT, and high rents. From that perspective, 10% seems great.
Not at all!
Using some simple online calculators, assuming you earn $125k in San Fran, your take home pay after tax is $85k. In Australia, your take-home pay after tax is $88k (and that includes the medicare levy deduction if you don't have private health cover).
So not only are you being taxed more in the US, you also have to pay for healthcare on top of it. Insane.
if you're working a regular job then that's not true because employers heavily subsidize your premium or pay for it in full if you're working full time.
if you're self employed then your health care premium is 100% tax deductible
and like others said you would qualify for either free or subsidized insurance if you were low income
