It's a great thing we can see what this looks like - a society without a moral foundation, in safe lab conditions. Later, we will point to SF as a case study. The decay nearly always progresses along this line: erosion of the moral foundation and the advent of nihilism, the rise of animalistic sexuality with no restraint whatsoever, the rise of animalistic cruelty, demonocracy where everyone creates an image in his own name, and finally anarchy. In this case, authorities will stop it right after step two, for unhinged cruelty is still a big no-no.
