The idea of your employer being in any way connected to your health care is just vile. I am sorry to hear about your personal situation, most of the analysis I've done shows that the exchanges are competitive with employer-provided health care, and in many cases cheaper with subsidies. If it turns out at the end of the year your employer insurance over-charged, I believe they have to refund you some of your premiums. They can't just pocket the difference and call it a day anymore. This is totally new. How well it will work remains to be seen. There is also the somewhat shady option of just paying the penalty for no insurance, and if something major happens, sign up then since you can't be denied for pre-existing conditions now...
As for the poor, the law was written so that anyone making 138% FPL or less would get Medicaid. From there up to 400% would get subsidies. But half the states aren't doing the Medicaid expansion. This is a pretty big wrench in the cogs, and it remains to be see how it plays out. The idea was to get people with no insurance out of the ER and into preventative medicine, which is much cheaper to provide. Plus the moral arguments about helping the poor and sick, etc.
I've been saying the same thing about the Republicans. If Obamacare is so awful, why not just sit back with a smug grin and let it fail for two years, then rake up in 2016? I have this suspicion they're afraid it might actually work. If all the poor, white people that voted for them suddenly can do see a doctor and get medicine and take care of nagging ailments under the auspices of "Obamacare", that's gonna devastate them at the polls with that demographic.
As it stands for my family, there is myself, my brother, and my nephew who I know off the top of my head could get in on the Medicaid expansion. We currently have no health insurance. My brother actually has diabetes, so he needs it pretty badly. As it stands here in Tennessee, Obama is still evil and those damn liberals, etc., since we STILL won't have coverage in 2014. But if the expansion had went in, the three of us would have Obamacare, and it would be a hard argument for any of us (or my parents) to say Obamacare is bad when we're suddenly getting medical treatment we've needed for a while.
