Healthcare is absolutely available to those without employment. Where have you heard otherwise?
In fact I wouldn't be surprised if the majority of the healthcare burden in the US is from patients without employment. Medicare and Medicaid are some of the largest funds out there.
Oh, I'm not saying it's not available to those without employment, I'm saying it's sickening that it is very often tied to employment, for those that have employment.
Ones employment and ones health should not be linked in anyway whatsoever, lest bad things happen.
