Similar concerns are discussed frequently even here in Holland. For example, where in the past people would mingle 'across' class through religious affiliation, secularization changed that dynamic. Gentrification in the cities is pushing immigrants and the lower classes out to the periphery while yuppies and rich people concentrate in the desirable center. While our schools are still pretty mixed, there does seem to develop and increasing schism between different classes. Increasingly homogenous 'family units', decrease in contact with extended family, neighbors, and via religious affiliation might have a much bigger effect on society than we are currently aware of. EDIT: Not to mention a strong increase in freelancers and as a result a decrease in long-term work relationships (with 'the company' and with colleagues).
