Teenagers are too young to really know what is going on in the world, and for the most part, what they've been taught in school is WRONG. Liberals (socialists) have been in control of the education system for far too many years and consistently "condition" our children to believe THEIR version of things--which uniformly favors collectivism (socialism) as a lifestyle. This is not a "conspiracy." It is a PHILOSOPHY that has been taught in our schools for a long time. It's understandable that today's teenagers believe socialism is a "good thing," that it is being used successfully in Europe, and that it should be brought here. It is NOT, and SHOULD not. Everywhere socialism has been tried it has either failed, or is only lasting by being "propped up" by other socialist countries newer and still solvent (who will not be for long) or even by US. Communism in Russia is just the biggest socialist nation to fail. Many others have failed, or are in the process of failing. Their economies are failing, one by one. In this hemisphere, Cuba, for instance, is still around, only by being "propped up" by Russia, and now by Hugo Chavez' in Venezuela, who still has money because he "nationalized" (stole) the oil companies Americans built for him.
But their infrastructure is crumbling, Castro is dying, and the only new cars there (if any) belong to high-ranking politicians still in his favor. Teenagers have not been ALIVE long enough to know what's going on. I know I didn't when I was a teenager, but soon learned the truth after I got away from the influence of those socialist conditioning mills we call schools. I was a Democrat in those days, and soon became a "Goldwater Democrat" in 1964. The guy who later came up with that TV ad showing a little girl picking a flower while a nuclear bomb exploded in the background, saying, "If you vote for Goldwater, we'll be stuck in Viet Nam for years" was right. I voted for Goldwater, and we WERE "stuck in Viet Nam" for years. Only it was because Goldwater DIDN'T win. I was disgusted with the apathy I saw in those days, and consciously :opted out" of politics for many years. That was my biggest life mistake, which I corrected just before Clinton's first term. I found out that even if I didn't "pay attention to politics," politics WOULD pay attention to ME. (Just common sense)
