It's cheaper to prevent than treat...
But in an ultra capitalist healthcare system, cheap is bad.
There's more profit in no preventive treatment so you can bankrupt people later.
The system is working exactly as intended, they're making as much money as they can.
Which is why even with Dems controlling the White House, Senate, and House for two years...
None of them even talked about healthcare.
Neither party wants to change it, because they get donations for not changing it.
