Not ALL Americans lack health care, but I challenge your statement that most working Americans have good health insurance. I believe most Americans have minimal health insurance set forth by employer mandates to provide HI, and a few in top notch jobs might have excellent insurance. The problem is not everyone is talented enough or good enough to land those super good jobs and there aren’t a lot of them to be had (well excuse us for being dirt bags!) There are a lot of mediocre jobs and employers are constantly look for areas to cut costs, one if which is the quality of the employees health insurance and other benefits.
Then you have the self employed sector who really gets ripped off. If I wanted super good health insurance I would have to pay more than what my house payment is including taxes and insurance. It also depends on where you live in the US. I live on the west coast. Our definition of low income is completely different from somewhere in Mississippi. Low income here is rolling pretty damn good in many other states, but Federal low income standards apply equally across the states. Federal low income standard in California is homeless. So for instance I just saw something on the news about what it takes to be considered normal income in San Francisco. They figured a million and a half a year just to be normal and 4.5 million just to “feel” wealthy!
The ones who benefit the most from Obamacare are the dirt poor poverty stricken who get everything, and the super rich who can afford anything. The rest of us have to pay dearly for it.
