Security, understandable structures and customs and a common identity being important factors for happiness - not that new, but important to stress. Its biological too, because people prefer people of their own if being not conditioned in a unnatural way since they are biologically-genetically more related and more adequate for forming a close-knit and healthy community for most cases. Homogeneity is positive for a good group identity and common sense, for social cohesion and responsibility. But those are things Liberalcapitalism doesnt want to have - at least not in a too strong form which could change the system - anyway. Thats the only reason beside their worldwide expansion and "One World" phrases for furthering "plural societies", its better for plutocratic business and oligarchic control.
