Ouch, hate the US? Certainly not. I hope that was tongue in cheek.
That wasn't directed at you, that was a sardonic rant in general (Republicans like to use the "Why do you hate America" line to score debate points on the cheap).
One reason why the American health care system costs so much is that there's a ton of waste in the system. I have a sick puddy tat

so I've been pricing out vials of a medicine she needs today.
From the vet: $108/vial
From Walgreens: $400/vial
From drugstore.com: $27/vial
What is the logic behind those vast differences in price? Well for starters, Walgreen's sells that medicine to human beings (it's the same medicine for people or pets) who are likely to have insurance and don't care that they're costing the government (and their fellow taxpayers)
fifteen times as much as if they got it thru a reputable online service. Hey, it's not their money, right?
The vet doesn't dare charge $400/vial - health insurance for pets is still unusual and at those prices, kitty cat will be headed for permanent sleepy-by time - but they do know that pet owners who care enough to take their cats to the vet will probably pony up a bit more than $27/vial (and who knows whether that's even the rock-bottom price - I should do some more checking!)
Who's pocketing all that money for $400 vials of $27 meds, hmm? Multiply that by hundreds of thousands of medical transactions every day. The taxpayers are getting ripped off right and left. Who in the system is motivated to keep costs down? Looks like the answer is "nobody" right now. UHC isn't going to inject that motivation into the system.
The point is that the only reason I've been checking prices is because puddy tat doesn't have health insurance. I have absolutely no idea what medicines that I might take would cost, and since I do have health insurance, I have no motivation to spend my time on comparison shopping.
I just started this thread basically because I've been watching news from the US (fox news) a bit recently
Fox News is in its own little universe, just so you know. CNN and MSNBC will give you entirely different perspectives on the same things.
