Kids today are soft thanks to the self-esteem and blue-ribbons-for-everyone movements.
Because kids weren't committing suicide from depression and bullying before whatever point you consider things went "wrong." :/ When you're a kid, your estimation of your own self-worth is not about whether the school gives you a "blue ribbon," its whether your peers do.
Its always been a huge problem, we're just hearing about it more, and more celebrities are standing up about it (George Takei's "it gets better" video, for instance). Plus, in America, parents seem to have this mentality of "how
dare you tell my child how to behave," even in situations that they're not present in (school, for instance), so parents can and have gotten into the schools and eliminated any real possibility of discipline (short of what ZBomber said, threatening someone, an actual fistfight, or bringing something illegal to school gets you suspended).
