Considering the fact that one of the big issues here in changing jobs is possible loss and the fact that last time I looked a fairly standard BCBS policy for myself and my wife was about $22,000/year, the notion that you have a choice in the US in health care is rather quaint.
I lived in the U.K. for a while. Our system gives a lot more choice than theirs did.
Yes, if you change jobs it can be a problem. But at least you can’t lose everything if you disagree with thew government. I live in CA, where they’ve euthanized people.
