That's just false. The US federal government spends over $1,000,000,000,000 on healthcare per year. Only Social Security is a bigger expenditure. It's almost twice what it spends on the military. It's 8.5% of its humongous GDP. That's a larger percentage than most European countries. Germany's the only country I'm aware of where the government spends substantially more of the country's GDP on healthcare than the US.
It should be noted, however, for spending a much larger percentage of GDP they are still only providing coverage to about 1/5 of the population while most other countries you're discussing are covering 100% of the population.
