Modern days society seems to worship emotional weakness in a terribly morbid way. I guess that's how our politicians and industrialists want us to be, weak and ready to break under the slightest pressure.
I think it's not that so much as parents not doing their jobs right anymore. Rather than being a parent they want to be a friend and refuse to discipline their children. Most brats need a good spanking to get the whine right out of them.
But if it only was a parent problem children would learn upon impacting on the real world- it would be the perfect shock therapy. But nowadays society teaches us that it's ok to be a loser not by promoting equality between persons, which would be good, but creating sub-cultures ready to give anyone a chance to feel unaccepted without even trying to fit into society. The fact that often d people have prejudices and neglect who is different is used as an excuse to recognize oneself as part of a group of rejects which only serves as a easy way out of the conflic before even beginning it.
