That might also be an issue of culture. I suppose it would affect different people differently but I highly doubt that most people would become bad to each other when they are less stressed and have more stability.
True, but often as far as I know research like that is about how people respond to sudden changes and local crises, not necessarily how they would react in a different social system. But I do also expect people to treat each other better if the conditions of their lives are better.
The studies I happen to know about focussed on population density and resource abundance/scarcity. While not an exact analog I think they do give a decent estimate of this situation

That however, has been studied
