Cancer? Bye.
Heart problems? See you later.
They were a fraud and you were getting ripped off.
ADA put an end to that fraud. Insurance companies could no longer arbitrarily throw you off. That's why premiums went up from $80. They had to actually provide coverage.
Now you know two things.
ACA forced them to cover everyone, which raised costs and, therefore, prices for everyone.
It's true you're now subsidizing sick people, but you'll be happy to have the ACA if you're ever sick (or have a dick family member).
They would take your money while you were healthy but if you got sick, they'd throw you off.
That's not insurance. That's fraud.
Edit: It seems my comment is being interpeted as for or against ACA, when the point was really that insurance companies will raise prices over every potential regulation change.
Now, there is only one company left in my state that will even offer plans in the private market. The closest plan to what I used to have has gone up ~6x in price and the deductible has tripled.
The prices started going up immediately after the ACA came into being I think the cause and effect are pretty clear.
