I like a lot of the parts of the ACA - the pre-existing conditions clause, the being able to have your kids on your plan until they are 26, and so on. These are excellent, forward thinking ideas that really help people. Another great idea in the ACA is the ability for some people to be able to get coverage that they otherwise would not be able to get, at a price point they can afford.
Unfortunately, there are parts of the law that were not well thought out, or were put there for political purposes. The ACA is a massive piece of legislation and there was a lot of room in it for these less desirable conditions to be hidden in the law, and now that we are able to "read it" we are finding out about them. Things like requiring maternity coverage for a 70 year old man which makes no sense. I have read lots of stories about people's premiums doubling or tripling for new plans with much higher deductibles and less coverage.
Out of curiosity I looked on a state exchange and a plan that has a similar monthly cost as my existing plan provided by my employer would cost me a lot more in out of pocket expenses to meet the deductible. A serious medical emergency would effectively wipe me out before the deductible is met.
I think that ultimately the voters will decide the fate of the ACA one way or the other.
