I think recliming seats are a royal pain!
The solution would be - everyone reclines, or no-one reclines, which of course is not actually a solution at all.
I try not to recline - mindful of the inconvenience to the passenger behind me, and then I put up with the reclining of the passenger in front, who doesn't share my sense of community spirit!
One thing they could enforce is a dress code on planes - no wife-beater vests allowed - oh and no B.O. as well, although they usually come as a passage, with obesity thrown in as a freebie!
