Why Don't Conservatives Understand Insurance

The conservatives always say that liberals don't understand economics or business. I was reading the paper when it occurred to me that conservatives don't understand how insurance works. Maybe because it is essentially a liberal construct. Insurance works because of a shared risk. Conservatives are fond to say "I don't want to pay for your birth control, insulin, asthma drugs,...". Some of these conditions are charged more because the company has to payout more, but these premiums are subsidized from the healthy people's premiums keeping insurance affordable for all. If you change to what the conservatives want, the high risk patients will be eliminated.
