You said that "health care costs are spiraling out of control". Your justification for that is that you spend more money on health insurance than you used to back when you used to spend nothing because you got nothing. Making a blanket statement of "healthcare costs" and "out of control" needs to come with the following caveats:

1. They're spiraling out of control for you - 2. Because you used to pay nothing 3. Because you used to get nothing 4. Because you didn't worry about it.

Say all that. The price, for the average consumer, that buys health insurance has been rising for decades. It has not slowed down because of the ACA but it hasn't sped up because of the ACA.

You're making a blanket statement based on your atypical experience of not having health insurance and then making it seem like it affects everyone.
