In fact, I read a little essay wrote during the 18th century by a grumpy old guy that, if modernized a little bit, could pass for your little essay.
I think your reaction is an effect of aging more than an objective view of the world. It's probably very similar to what a pre WWII adult would say of the pampered boomers born around the 40s: children are treasured by their parents, fathers want their child to surpass them and parents are disappointed by the new path their offsprings carved, on average.
Basically, your comment is as useless to trigger change in the youth as it is interesting to study aging. Instead of wondering how to whip the youth into aging faster, I d ask you: how to comfort the elders into aging slower ?
