* They can't think for themselves.
* They can't work out any kind of reasonable answer to even simple problems.
* They have no real concept of history at all. Their ignorance of the world is overwhelming.
* They can't seem to tell right from wrong, only what they want.
* They are seriously controlled by peer pressure, mainly in a negative way.
* They are rude and obnoxious from an early age and onward, not just teens. They tend not to improve... nasty at 15, nasty at 35. Why should they change?
* They don't care about anyone but themselves and some of their peer group; they don't even care about the family that is providing the largesse, they're just a kind of bank account and guaranteed source of toys.
* They are ruled by greed to a point that I have never seen outside large corporations and politicians.
