Your argument fails to take account of:

1) Medicare for all aka Socialist Healthcare is practiced world wide. It's cheaper in tax terms for citizens because they aren't paying for company profits and for uninsured citizens to not die on the street.

2) Doctors don't just do it for the money. They do it because they also want to help people. The UK government has for the past ten years been doing effective pay cuts, unmeetable targets and other bullshit due to ideological extremism, i.e. that anything "big government" is bad and that profiting off people being sick is ok. Doctors still work there because they believe in the work.

So the thing that would benefit you and vex health insurance companies money terrifies you DESPITE world wide evidence that it's a good thing.

Think about where you got these attitudes.
