If you are allowed to buy "health insurance" after you are already sick, it's not "insurance" at all. Sorry, it just isn't.

Do you also think that you should be able to buy fire insurance after your house is already on fire, or car insurance after you've already had the accident?

Note again, and note well, that I'm not saying that people who are already sick should be abandoned. That is a real problem and one which should be addressed. I'm saying that bundling them into an "insurance" program makes no sense whatsoever.

It makes even less sense when you bundle them into Obamacare, the other users of which tend to be poor. I mean, they weren't able to afford insurance before... and now they're expected to not only cover their own costs, but the costs of all those with preexisting conditions? How did anyone expect that to work?

If you insist on funding the preexisting folks by charges on another risk pool, it probably should be done across the board (i.e., by charging the costs of the preexisting folks to all recipients of health insurance, not just the ones unfortunate enough to be stuck with Obamacare). That, at least, would have spread those costs over a much larger pool.
