The troubling thing here is: what is a "better" society? As you said, it's just the one that outcompetes the other societies on the globe. We'd like to believe such a thing is an egalitarian "healthy" liberal society, but it's just as likely to be some form of enslaved/boot stomping on face society. Some think people won't accept this, but given human history I'm pretty sure they will. I think these sorts of societies are more of a local minima, but they only need to grant enough of a short term boost to unseat the other major powers. Once competition is out of the way they'll probably survive as a bloated mess for quite some time. The price of entry is so high they won't have to worry about being unseated by competition unless they really screw the pooch. I think this is the troubling conclusion a lot of people, including those in power, are reaching.
