only parts of the US are unwilling
they happen to be in the Fortune 50, or top 10.
serious, go look at the F500 list and see how many of the largest, meanest companies in the US (and world) world also happen to be healthcare
if you wanna know why it's never gonna happen -- there is the list. they will spend more money than god on social media, bribes, and whatever else they need to keep the system the way it is
Why is Fortune the relevant list? Why not market cap, which also happens to correlate with net income, which means more cash to spend on political influence?

Mostly only pharmaceutical healthcare in the upper tiers of that, but these businesses still have market caps and net incomes literally one or two orders of magnitude separating them. Grouping top 10, 50, and 500 makes no sense.
