Current youth seems to suffer from many more mental disorders (such as depression) than before. Share of people who had sex by their early twenties dropped significantly, which may be a consequence of having less intimacy and more solitude. Non-academically-talented young men seem to be less successful than ever before, to the degree that even liberal coastal media stopped making fun of them and started describing the situation as dire and in need of addressing.
Such problems may be fake (percepted, but not real), but they can, in fact, be real. We are not doing ourselves or anyone else a favor by invoking glib, thought-terminating clichés about the old eternally grumbling about the young.
There must be a middle way between the "get off my lawn" and "this is an ancient trope that only deserves mocking" attitudes.
