Obamacare is not healthcare. It is insurance company care. It may have been all that he or the Congressional majority could sneak past the nasty Republican minority but it is not reform. It is entrenchment of the mulitilevel healthcare disparities that already plague the US of the Third World. The monied classes who own the pharma companies and hospital companies did not want all Americans to have access, so they don't.
For those of you who think that insurance companies given more money become less greedy and more compassionate, try giving a crack addict one little rock for free. It is a tactic used by dealers. One free rock=More business.
The PRE-Obamacare situation was multileveled to begin with:
1-super wealthy like the Bushes, who just pay the hospital bill with a card,
2-level A private insurance holders (like US Congresspersons)
3-level B private insurance holders (like disappearing union members) whose copays are getting higher and higher and whose self pays are getting higher and higher
4-Medicare holders (you may have heard that doctors like Medicare, but it's not true, check numbers one&two above for what doctors "like")
5-Medicaid holders - the poor people who get local govt help, but this pays so little of what is billed that doctor's offices simply turn them away at the door, or act weird at them inside the office, even insulting them to get rid of them. Yes it does happen.
6-Uninsured-the poor people who aren't poor enough to get help, and end up dying right BEFORE the Medicaid holders above.
The only real solution is single payor, or Medicare for all (socialism, OMG).
