You're almost certainly an American, who thinks that a) healthcare throughout the developed world other than the US is just like the NHS, and b) the taxes that go to pay for the NHS are inconsequential.

jdminhbg gave Germany as an example of a country that doesn't follow the NHS example. The German model of insurance based on public and private sickness funds, separate from hospitals and doctors, is a) closer to the "average" among developed countries than the monolithic NHS model of unified ownership of payer and delivery, and b) more or less what the US has post-Obamacare; the main difference is that it is harder (not impossible) to evade the mandate in Germany than in the US.

I'm not. I'm Canadian, and the taxes per capita we pay for our whole health care system is less than what the US pays per capita for just medicare/medicaid.

In Germany, the public option for health insurance runs you 14.6% of your income[0]. That is not a non factor.

But it's capped at roughly 400€/month for each employer/employee

For tech people in the US it is also a non-factor. The much greater income allows for buying great insurance coverage.

The UK is one of the countries with the lowest social insurance taxes in rich Europe. NHS is also one of the worst experiences of healthcare I've ever had and good companies in the UK routinely offer private healthcare (eg. BUPA).
