With the ACA?
The government is forcing you to pay?
The program is no good?
The insurance companies are making out?
You don't get what you were promised?
It will ruin the country?
It is socialsim?
It won't help?
It is Obama's program?
It is the liberal agenda at work?
What?
I'm going to say that it adds yet another layer of bureaucracy to an already heavily bureaucratic system. Each layer adds another level of costs, thus it increases costs.
Most of my other issues with it, I had with the old system pre-ACA so I can't blame the bill for those issues, but I can blame the bill for increasing those issues while promising the opposite. (further entrenches the insurance cartel, further entrenches big pharma)
It encourages hospital conglomerates making the independent hospitals more costly. We will soon have a handful of hospital corporations.
It ignores freedom of religion.
They used the shittiest republican idea ever of the individual mandate. It's like "get out of the way, we got this" then use an idea from the right that was so bad it was soundly rejected by all when first presented.
It mandates a level of coverage that not everyone wants and takes away choices you do want. I never go to the doctor, why can't I just buy hospitalization?
It gets involved too much with the patient/doctor personal relationship.
If you include meaningful use that was a trojan horse in the stimulus for preparation of the ACA, I have more.
Things I like, the pre-existing condition mandate. Keeping a kid on your plan until 26 (although a better plan would be no age limit, let me pool with my family and neighbors)
