Cool. If you grew up in downtown Detroit, would you still have had 4-5 teachers who taught you about money? How many of those teachers would be millionaires, or predisposed to wealth? You're assuming equal distribution when you have absolutely zero reason to. Richer teachers are likely going to live in richer areas, and will likely have richer students, who (according to your own argument) will not need advice on money because they'll already have it from their own family.
Think of it this way: the odds of getting attacked by a shark is 1 in 11.5 million. Do you think the person who lives on the beach and swims in the ocean every day has the same odds as the person who lives in Milwaukee and never takes a vacation?
Because half of them don't need to work whatsoever and the wealthy who work for fun tend to not go into the post office or police departments?
