Dysthymia in Japan

What is the effect of public policy on younger males? Joel Kotkin observes this about young males in Japan:

Just such a diminished world view has already taken root in Japan, particularly among that country’s younger males. Growing up in a period of tepid economic growth, a declining labor market, and a loss of overall competitiveness, Japan’s male “herbivores” are more interested in comics, computer games, and Internet socializing than building a career or even the opposite sex. Marriage and family have increasingly little appeal to them, sentiments they share with most women their age.
