in a relatively homogenous society, it can be much easier to envision a unity of purpose, a shared vision for the future & some semblance of an objective Truth
but w/ social heterogeneity comes social friction, which erodes trust & makes markets more attractive as intermediaries
markets, while great tools, don't exactly to encourage interdependencies; they enable the emergence of atomized lifestyles, w/ working couples following the money, often moving away from their families & social circles
its tougher to put down roots w/o direct relationships
