The "social changes" aim to change LW in which direction?

I don't think there's a good short answer to this, because if I try to point at individual shifts and say "shifts like those shifts" I need to give many examples to give a clear picture, and if I try to point at principles guiding the shifts and say "shifts that follow those principles" I need to give many details about the principles to give a clear picture.

So I'll give a long answer, but that'll take time. (Maybe in the course of writing a long answer I'll discover the short version.)
