Respectfully, if you are holding out some hope that aircraft seat size might be regulated for evacuation times, resulting in larger/more comfortable seats, I would urge you not to hold your breath waiting for that. Never gonna happen. Ever.
The miserable seat sizes now in use are the result of one thing: the airlines are giving customers exactly what they are asking for: cheap, cheap, cheap. The public has come to demand (and now expect) ticket prices to be impossibly low. They want crazy cheap seats, so the airlines are saying OK, here you go. The FAA isn't going to fix that.
It seems to be working well for both parties. If it doesn't work for you, don't blame the airlines, blame the people buying those cheap tickets in tiny seats. "The wisdom of crowds" sucks if you're not part of that particular crowd.
