What the young people might want to consider is this: As soon as they become ineligible for the continued free ride, they're going to be paying up the wazoo under ObamaCare. Their rates will have to be much, much higher than they'd be under a free market system, because they're going to have to subsidize not only those with "preexisting conditions," but also the elderly.
Right now, they have the choice of purchasing less expensive, high deductible insurance that would allow them coverage for catastrophic expenses. Under ObamaCare, that option will be gone, and they'll see a solid chunk of their paycheck going to their health insurance -- to pay for coverage they don't need, in order to subsidize the cost of others -- for the rest of their 20's and 30's, at least.
There's no time like the present for people to realize that -- to use a hoary old cliche -- there's no such thing as a free lunch. Let's hope the young learn it now, 'cause you can bet they'll learn in (and not in a fun way!) if ObamaCare is imposed on all of us.
