Utilities in most areas are run by private corporations. Try telling me with a straight face that they do a good job.
My power company is privately run - they don an exceptional job. If the power goes out they work tirelessly to get it back on, even in the worst weather conditions(and compensate their employees well in such situations to boot).
Here's a good one: health care. Are greedy HMO's any better than socialized health care?
Greedy HMO's? Well, I don't use them, and HMOs do have problems. Frankly though, most of my experiences with private health care have been very positive.
Here's another one: education. Overall, I've received a much better education from public schools than from private schools, after spending a roughly equal amount of time in each.
Your experience alone is not a valid way to show that one generally outperforms the other.
I think the main reason why these government services work better than their privately owned counterparts is that they are less focused on making money. (My experience has been that even private schools try to make money.) Profits are not a big priority outside the corporate world.
Then why don't we just advocate communism? Oh, wait, that's right - because when the government tries to run everything it results in crap. Government does crappy when it tries most things because it has no competition - it has no fear of going out of business. Private enterprise on the other hand MUST perform well if it is going to stay in business. Private enterprise wants money, sure, but to get money it can't provide afford to provide a crappy service for high prices unless it's a monopoly.
