I would need some proof of that. From what I have seen, the majority of financially independent people are college educated and did so earning a crust from someone else and then investing the money wisely and with due diligence. Some have been independent business owners and in that group the numbers of college educated is probably slightly above average in my experience.
Exactly. What I have bolded holds true. Some are business owners, others like one of my family members, are college educated or even plain hard working people who were smart with their money. She was a school teacher making ~$50k per year. She stayed in the same house, lived within means, paid her home and vehicle off and saved. She is now entirely financially independent and retired and although she draws retirement, she has the ability to cancel it if she wanted, live a comfortable lifestyle (the same, if not better that she was living while working) and never have to work another day in her life.
There is a book that I read a while back that said most of the time millionaires are the ones who live in middle-income communities, live in the same house for most of their life, drive 6+ year old vehicles yet have millions in their bank account. Then you have "credited millionaires". The ones who make $5000 a month house payments, have 13 credit card payments, lease their BMW and if they missed a week of work would go bankrupt.
