Every last word was true. It's almost impossible for a work at home person to get health care. For those who work in a "regular" 9-5 type job it's only marginally easier. You have to join the employer at the right time or you often have to wait until the insurance company "opens" for new registrants. You can also expect to pay a premium penny for the insurance especially if you need family coverage.
You can go to any emergency room and be treated there. But that is usually a last resort as you can spend thousands of dollars for what turns out to be 5 minutes with a nurse and 4 minutes with the resident doctor.
And even better (I think) is at least here where I live if you don't have a 9-5 job forget about getting any kind of gov't assisted insurance. Not unless you want every one you've ever known about to know you went on welfare.
But any way... that was just my two cents. As far as links to articles about healthcare...
This one doesn't seem to have been updated recently (they give number for '05 and projections through '09) but good information I think.
