I think people forget that the game evolved, and those evolution choices were driven by player behavior. This isn't really new stuff -- like you said, it's literally why the system changed before.
More to the OP's point, though, is that these behaviors seem a lot more wide-spread than the first time around. It's like there are 100x more selfish people now than 15 years ago. Maybe society changed, maybe I just notice them more now, maybe it's some other reason. IDK, I'm not a sociologist.
