Oh. That I can explain, it is quite obvious why it would help the situation. There are three possible situations:
Situation 1) No law requiring people to buy healthcare, no law blocking insurance companies from denying you healthcare for pre-existing situations. They can even deny you healthcare for brain cancer because you have diabetes. (or worse, accept you, then deny coverage because you failed to disclose you had diabetes). People that get screwed: a) anyone that is not 100% healthy and also b) anyone that risks going without insurance but ends up needing it.
Situations 2) Law requiring coverage of pre-existing conditions, but no law requiring people to buy insurance. People that get screwed: Insurance companies, as people wait till after they get sick to buy insurance. Then after insurance companies all go bankrupt, everyone gets screwed.
Situation 3) Law requiring coverage of pre-existing conditions and also a law requiring people to buy insurance. People that get screwed: Anyone that wanted to risk going without good insurance and would have been lucky enough not to need it.
The first situation was what we used to have. The second situation is what we tried to avoid.
The third situation is what we have now. Please note it only screw up assholes that tried to take ridiculous gambles and happened to be lucky enough to win the gamble.
We had a choice - screw over the sick, screw over insurance companies (which would have eventually led to a truly government controlled healthcare), or require everyone to buy insurance. We wisely made the best possible decision.
P.S.I am employed and have good healthcare - which I desperately need because I got sick (nasty virus) in college and my kidneys have slowly been dying over the past 20 years, despite the fact that I don't drink, etc. I have maybe 5 more years till I need a transplant and am clearly one of the people that will very much benefit from Obamacare.
