i think planting the seed is the most imprtant part, need that seed to grow for a few years into their mid 20's when the brain fully develops. very important, there is an old college humor.com joke where someone says to the class " by the time you are 30 you will all be republicans anyways"Musicians, actors, media in general, CNN, stand up comics and facebook are where a lot of people get their "news", you are correct. It's a very low standard, and it's not that hard to show fault in it.
Most I have talked to do respond well to simple logic, when you point out the motivation for what ever is happening is due to greed, not capitalism. They can see through it, and they understand that they themselves are trading something they have for something they want, and when you explain that is the basis for all capitalism and all you have to do is keep power decentralized they can see at least enough light to realize it doesn't all have to be bad, and it actually may be the best system we know.
Not saying they are all convinced or anything but the seed is planted to at least help change the direction of their pendulum.
