> So my question is, how does Medicare for All cut costs without collapsing the healthcare sector?

Administrative and collections costs, which are a large part healthcare industry already (probably more people work in billing than in actually doing the healthcare work). Our current system is a huge mess, mainly related to all the complexity of our insurance system, and just by getting rid of that complexity huge savings can easily be had (though at the expense of a lot of administrative healthcare jobs).

There is a good reason why the USA pays far more than most countries for healthcare received.
