Medicare is more efficient than the overwhelming majority of private insurance companies.Insurance companies would operate very differently if they could charge prices based on what their customers would cost them. It would also help if employer-provided health plans didn't have such huge tax advantages. And Medicare provides a different set of services.
It would be as if the government mandated that 1) instead of buying meals, you had to buy the right to eat at a restaurant--but the restaurant could not charge different people different amounts based on how hungry they were or what they liked to eat, and 2) companies could buy food for employees at a tax-advantaged rate. If that were the case, food would suck, and one could imagine free government-run cafeterias that provided cheaper, better service.
Social Security also has super-low overhead, less than most funds (although lower returns than many funds as well).
Their return is zero, minus administrative costs. When you invest money in a mutual fund, they buy stocks with it; they don't use it to pay off the previous investors, and spend the rest on their pet projects. That's illegal.
The federal government is actually better at pure administration than the majority of private companies, because they're constantly under the threat of getting the axe and have a mandate to do their job rather than take paychecks home.
I would like to meet some of these government employees who actually fear losing their jobs. Where did you find them?
The lower salaries don't hurt, either.

Government workers make vastly more than private sector workers.
If you're ideologically opposed to the existence of even a perfectly run Medicare and SS, of course, that's a different story...
It's clear from the data that I don't need to be.
