In a lot of ways - these network effects read more like privileges than anything. With most of them having been begun with - what family were you born into. Almost everything else will follow after. It is why people who are born into such desirable families can end up with so much more desirable things so much more easily. The effects of being born into that family will lead to a good high school which leads to a good college which leads to a good first job... And if your family raised you even half decently then you'll end up with a spouse who is likely similar to you because where you go is somewhat correlated with your upbringing. Many people meet their partner in college or the workplace after all. (And the activities you will have interest in can be correlated with your upbringing - and/or your ability to afford them)
