The Big Bad Wolf.
If you're asking why Obama didn't expand medicare to cover everyone, the answer is because the Insurance companies, who's lobbyists have a lot of power in Washington, wouldn't let him.
Do you not remember all the discussion about a "public option"?
That too.
(sorta the same thing,though)
Thats pretty much it: not politically feasible.
The irony is no one likes the ACA.
Its supporters do so only because they understand its a first step to an eventual single payer system. They see it as a foot in the door, as it were.
Basically yeah.
But, in fact, HMOs were all for it until they discovered they would actually have to pay for treatment and couldn't just siphon off endless profit without investing some of that cash back into improving the process. And big pharma was aghast that the government would no longer be locked into buying their expensive brand name drugs over generics.
That's basically the root of all the hubbub.
So they came up with "Death Panels" and "Forcing" people to buy "private" policies.
And the conservatives fell for it.
Hook line and sinker.
