tangent, but: i think reclining your seat in economy class is incredibly selfish. i wish they'd weld them all.

From what I can tell there are two populations: those who prefer to recline and those who prefer not to. As long as an entire column of seats belongs to one population you're fine (if everyone wants to recline no one loses space, we all just shift around to a configuration in which everyone is more comfortable). But when you have someone more comfortable staying upright sitting behind a recline-preferenced person, that's where issues arise. It's not clear to me whether it's morally wrong for the front person to recline in that case, given that's basically just preferencing the default of "upright", which is arbitrary.
Nothing here should be read as justifying people who don't pay attention to what's going on behind them and/or recline suddenly/aggressively. It's always something that should be done with a glance behind and a smooth, gentle motion. Maybe also a word to the person sitting behind though again I'm not convinced that's a moral imperative.

(I wonder if it simply driven by an individualistic vs. collectivist mindset?)
