To me it just describes human nature and this human nature (or even a need) has been around far longer than McDonald's has existed. Everything in your life is there now in order to overcome some past inefficiency or inconvenience - it's not like we are using carrier pigeons or even the postal service to communicate here.
If people want to discuss issues with PF I will, but that's not what I read into the OP's posts. Everyone is going to read something different into the original based on issues they have with the game or maybe what they love about it. You bring up PF, others bring up generalization of classes. Many times the issues players have in a game are created by the players themselves. They give feedback about something they don't like, devs change it, then they complain about the change. Again, this has happened in just about every MMO I've played.
