Yes; it would be run be run much better, if govt is paying for so many medical services already anyway. For the 3rd time now, its the perfect recipe for fraud when you have the govt guaranteeing and paying for services for so many people anyway, but the private corporations are the ones getting reimbursed by the govt for performing these services. Fraud would probably be < 1/10th of what it currently is with the fat and greedy corporations all trying to rip everybody off.
You wingers want to continue to pay for Medicare and for emergency services for poor people. If you want the govt to pay for it anyway, get the grubby hands of the insurance companies and other profit-seeking corporations (all trying to maximize their cut) out of the picture.
Your argument about USPS is just plain stupid. They have a deficit because they haven't charged customers enough over the years, given their expenses. They're TOO good of a bargain and we don't deserve to get the services we get from them for so dirt cheap.
