Doug:
1. Please specify these communities of the wealthy with complete demographic description--ethnicity, religion, race, and so on.
2. "Intergenerational cycle of privilege" OR intergenerational cycle of success? You are begging the question in assuming that heirs do not build on and enhance the achievements of their forebears and are merely parasitic.
3. "Studies show" that the main advantages of private schools lie in "connections" rather than in academic performance. This observation is not supported by the conclusion of the Statscan study linked in the article (and this is the only study referenced). So source or retract. At any rate, parents, even <1% parents, send their kids to private schools for many reasons, not the least of which is to escape the chaos of, for example, TDSB schools.
