Millenials see themselves as more calm and collected than prior generations. They are not crazy for drugs, alcohol and smoking and can accept random casual relationships with ease.
This is all a reaction to what was happening in the world in the 1990's and early 2000's. Millenails were brought up on video games and virtual reality. Millenials have never experienced a national draft, extreme poverty or deprivation and they see politics as an excercise in compromise with no black or white - only grey areas.
They have never heard of the Pol Pot killing fields and see no need to learn about the cold war, the Cuban Missile Crisis and the past. Common culture passes for an education among some millenials.
They have never seen large scale war or tragendy and feel immune to the possibility. Blame the TV happy talk news, blame the soap opera TV and Movies pushed by hollywood movie industry, just don't blame the parents. Unless you were living amish style - the kids were indoctrinated with the touchy/feely non-judgemental stuff that keeps them so artificially happy.
Maybe that lack of materialism is good for our world. Maybe a culture in which people more readily give of themselves is a good thing. I tend to think it's delusional, and that for every person who's willing to give, there are ten people willing to take. And there will always be those deadbeats who refuse to carry their share of the load.
But that's not my world. My world is one where I keep the property I earn, and where I share it with those whom I choose IF I choose, not when it's coerced from me in the name of some government tyrant.
