If society is going to fall apart anyway, because of nuclear war/climate change/Trump/demographic collapse/soil depletion/microplastics/forever chemicals/peak oil/whatever, why should I care about trying to build a future? It won't come anyway. Why should I care about the quality of my work? Why should I care about having kids? Marriage, even? Why should I care about anything? "Let us eat and drink, for tomorrow we die" (bad advice in any era, but seductive to those fighting against apathy).
