Someone asked this question in another thread, and there are detailed, real-life experiences in the replies (not vague, undocumented generalities)

There is also shitty insurance, mostly from shitty employers, but much more so on the private market. (Large pool) employer insurance otherwise is usually pretty good. But let's be clear: poll after poll over the years has shown that most people like their employer-based insurance. That is the reason why the health care bill ended up as it did: people DON'T WANT to give up their insurance. Don't blame me for that. I didn't make it up. It means that people are going to have to be weaned off their private insurance over time ... and this bill will accomplish that over the next decades.
Furthermore, you show ignorance of what the bill contains: there are many new regulations on insurers. They will have to cover more stuff; they will have to spend certain amounts of their premiums or give it back ($1.1 billion in checks are being prepared to be returned to employers and citizens right now); to be on the exchanges they will have to meet minimum standards--just like the insurance that Congresspeople get.
You know what? The time to argue this law is over. It's the law, and it isn't even fully implemented until 2014. Once it is in place and you see how it works, you can lobby for improvements. In the meantime, you're just barking with the Republicans, and trying to reargue what is already done.
