All well and good about healthcare being available and not-as-bad-as-people-say provided 'good healthcare by the company.' But there lies the problem, the dependence on those variables, "good", and "company."
a) What if you're self-employed? You're stuck with mediocre, expensive healthcare for the individual market.
b) What if the company is cheap or negotiates poorly the healthcare options? Sometimes they're mediocre.
c) Costs have been going up, and companies are finding ways to reduce costs (since someone has to pay for those padded healthcare executive salaries and healthy stock prices thanks for solid profit). Thus the same plan(s) get worse year after year.
d) there's a push towards 'high deductible, self-managed / pre-tax account' type healthcare, which is smiled upon as a fantastic way to give people choice. The reality is different, now not only is the healthcare company still the middleman that keeps a chunk that gets paid out to providers, but now it's up to you to 'negotiate' what healthcare service is important to you. Oh gosh, is it expensive? I'll skip this particular service.
The U.S. has got it all wrong, of course. I'm jealous of Swedish or other healthcare systems when I read through threads like these.
Bottom line: the mediocre healthcare system in the U.S. and the emphasis on giving middlemen lots of money for no reason is a barrier to innovation and self-employment. Why strike out on your own and take a risk on building something if you'll lose your precious company healthcare? This problem is only getting worse and clearly has an impact on the political discourse.
