I'm saying I'm not sure how you'd measure "educated". Many subjects aren't well suited to testing, and even for those that are, the tests don't often correlate all that well to problem-solving ability, insight, or other valuable skills.
You can measure wealth, but I'm suggesting that wealth outcomes has more to do with your life circumstances than with how much knowledge you acquire in school (by whatever mechanism you would measure that).
A network can have significant impact on your "life prospects" though, which is what you indicated in your previous post was one of your considerations for choosing a school.
