I agree it is a stupid system though and I'll tell you why: People want something for nothing. They want coverage for everyone, they don't want a tax, but they don't want compulsion to purchase and they also want to force insurers to take people with pre-existing conditions. Insurance can't work that way, the money has to come from somewhere.
If there was a compulsion to purchase, the system could work, as it does in many other countries. That's probably unconstitutional though, so it probably wouldn't stand.
Lastly you have "Medicare for all" which would basically bankrupt hospitals if you extrapolate from what current Medicare does to them financially.
You honestly can't blame representatives for dealing with voters that understand nothing and want everything. They voted for Obamacare, then they voted for Trump to make Obamacare even worse. I don't even want to know what's next...
