The few people who have gotten thru to the Obamacare websites are reporting policies costing several hundred dollars a month, with deductibles of $4000 and up. Such a deal. If you are in good health, which most of us are, you won't rack up $4000 in doctor's bills inside a year. So what are you buying insurance against? You still have to pay out of pocket for everything under $4000.
Support you get unlucky and actually need an operation? Those go for $20,000. So you pay $4000 and the insurance pays off the rest. Big deal. How many of us have $4000 just lying around? Damn few.
Most young single guys won't fall for deal like that.
