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.
Furthermore, #78, I get the feeling that you just didn't HEAR ME. Hypercapitalists are in firm control of the USA and there's no real way to dislodge their vicious hold upon the national mechanism without resorting to outright civil war. Americans are far too complacent with (even accepting of) the Imperial Model to ever fight back, regardless of how armed they are. There's still plenty of food, gasoline, electricity and entertainments of all kinds. We have a good 50 years of distraction before enough millions of Americans finally wake up poor, half-dead or full-dead, before Americans finally snap and start the shooting in earnest.
Since the Jews and WASPs with all the money have nearly complete control of the nation, there's not going to be any of your CAN/MUST wishful-thinking bullshit. What WILL happen is all of my CAN/MUST plans. Your insurance company is not going to cover your pre-existing condition, guy. Michael Moore can vomit up 1 "Sicko" movie each year and that's not going to change.
What MUST change is that you either change your lifestyle or you fucking die. If you don't fucking learn, then your death will cause your brother to learn; if HE doesn't learn, then HIS death will be a lesson for somebody else. We've about 300 million people in the USA ... we can lose a few tens of millions to an UNhealthcare industry without people causing any significant fuss.
There's no getting around it ... and there's no great Cultural Revolution waiting in the wings to make your fairy-tale wishes become reality.
