We can't afford it. Some people like Michael Moore say that we should just divert funding for the war toward Socialized Medicine, but the fact of the matter is is that we can't afford the war either. We are already borrowing money to finance a lot of the dumb programs already in place. Government spending is out of control, and we need to exercise budget restraint now, not consider new areas to increase spending.
#62 makes a good point. I happen to have ego enough to expand upon it in my own way. Insurance-dominated healthcare in America really didn't happen until the labor shortages around WWII. Employer-covered healthcare was one of the benefits which companies added since they were largely not allowed to offer larger wages or salaries due to government price controls. Hence, what was America really like before that? A living hell? Certainly not. America wasn't a living hell before air conditioning and weekly trash pickups, either, yet yuppie fucks somehow think that it was.
As the presence of Hypercapitalist insurance companies continue to distort healthcare in America beyond all recognition, perhaps it's time to stop subscribing to the idea that healthcare is a necessary item for a large percentage of the population. That same percentage could help that along by eating right and actually exercising for once ... what with individual responsibility being so allegedly important in America and all.
Remember, the REAL heart to "pro choice" is at the time when legs are spread to receive some whigger's cock. Similarly, the REAL heart to healthcare in America is keeping yourself fit for most of your life. That might require less posting to 4chan, alas, but that's the price we all must pay.
