The excitement that comes from being young is directly linked to having nothing and taking stupid risks to get more. When you get older, the risks disappear, but the desire for excitement stays, so everyone starts acting like their younger self again, except now their recklessness is directed at each other instead of the world. Cheating, drinking, fighting, lying, stealing, spite. Everybody wants the thrill back, but no one remembers how to get it cleanly, except having kids forces you to go back to the real risks, because suddenly you have nothing again, except this tiny, screaming thing that needs everything you have, and suddenly the stakes are sky high again, and the world is sharp and clear, because you have to go find fire again for real now
