Socializing ANYTHING is totally against everything in the Constitution. Many people, probably including members of your own family, have went into battle to make sure this country doesn't fall into the hands of socialist/communist hands.
Ah, jarbake, by your standards I've some bad news for you: all your dead relatives died in vain. We already have lots of socialized programs in this country. Lots of institutions against your interpretation of the Constitution. I know, I know: Welfare, and I'd eliminate that in two seconds! Nope, not welfare, although you'd be crazy to eliminate it, and public welfare programs -- safety nets -- have a place in any civilized, compassionate society.
Your police department. Your fire/rescue department. Your county hospital system, especially in major urban areas, as they are most likely to have them. Your public libraries, not that anyone uses these much anymore. Your public school system -- funny, that one is actually guaranteed in the Constitution rather than prohibited. Your post office. All "socialized", chiefly based on the public good concept that rob@ has illustrated. Many of these socialized American institutions actually run rather well. The US Postal Service actually *makes* money, and does a fairly amazing job of quickly sending mail all over a very large geographic area for a reasonable price.
Also, we've not fought one war to keep our country from falling into the hands of communists -- unless you count the Cold War, but it being "cold", nobody went into battle. We've fought a couple "hot" wars to keep *other* countries from falling into the hands of communist factions within those countries, with the alleged goal of quashing the spread of communism, which could potentially, though perhaps not all that likely, cause our country to come under attack by communist invaders.
And who originally mentioned lazy road crews? Rob@ is right: these lazy, leaning road crews you seem to see when you're out on the highways are almost always private contractors hired by the government to complete projects. That's your free enterprise system at work for you -- or not, as you seem to regularly observe -- at your tax-paying expense.
Finally, the tax argument. This has been explained regarding public healthcare so much that everyone should get it by now, but here we go. Taxes would rise to cover various nationalized services. But out-of-pocket costs would come down. In many or even most cases this results in a net savings for the individual or family. It's at least a break-even proposition.
Also, you make something bordering on an ad hominem attack on rob@ by stating, just about in so many words, "if you're so smart and know so much about this and that, you'd think you'd have something better to do with your time". I can't speak for rob@, but I certainly have better things to do with my time. In fact, every couple days I pledge to swear off the Internet altogether -- except for maybe paying bills; it's good for that. The thing is, if you have the knowledge and education in particular areas, it's something you've studied formally or informally, well, there are basically two types of people in these matters. You've probably encountered them in physicians you've had in your life. The first type is the ivory-tower sort, people who seek to contain and control all knowledge they've gained. You know, the doctor who won't explain anything to you and when you ask a question he glares at you before providing some vague, worthless answer. The other type is the doctor who sits down and will expound at length on topics medicine, answer all your questions in detail using the technical language of his profession, then define any terms you don't understand. He's passionate about what he knows and his impulse when he's asked or notices someone is wrong about something in his field is to share that knowledge, rather than keep it locked up like some secret holy talisman. So that's why I'm here when I indeed have a dozen things I should be doing.
Again, I can't speak for rob@, but I'm not writing here to correct you to make myself feel better or prove myself right, but because there are some substantial, basic and rather large flaws in the understanding of economic systems of some people posting in this thread. Indeed I'd prefer not to correct people at all, because it often makes them defensive, angry and sometimes worse. But when you see it stated one way and you know it to be otherwise, it appears the best thing to do for everyone's sake to note the fallacy and explain why the statement is mistaken. So it's one thing to fully understand economic systems yet still argue for live-and-let-die capitalism; it's another thing entire to have a flawed grasp of these systems and argue what is and isn't acceptable in these systems and under American law.
