Because everyone's goal in life is to own a business, invest in the stock market, and retire as fast as possible? Right. There are plenty of professions that honestly require a formal education: engineers, doctors, and lawyers are a few more "practical" examples. Behind them creating the framework which they rely on are research scientists. And I say this as somebody very critical of "schooling."
Ummm not everyones goal is to own a business, invest in the stock market and retire as fast as possible but if you asked everyone in the world where they would 'want' to be when they're 50-65 years old they will most likely say retired and rich. And here they are going to school so they become retired and rich but 99% of the population isn't rich and quite often when someone does end up retiring they don't have any financial breathing room because school doesn't teach you anything about finance.
There's a reason why so many people are attracted to the idea of being rich and retired but only 1% of the population actually is. I'm not saying don't educate yourself because knowledge is extremely important, I'm saying instead of listening to someone who teaches for a paycheck go out and actually DO something.
When I say school, I'm not talking about the courses that are offered by individuals who started their own business so that they could teach you their findings, mentor you, mold you into success. I'm talking primarily about government funded schooling.
You know why kindergarten, elementary, middle school, highschool are all free? The government is sending you on an specific path where they can tax you and make back more money from you then it cost to put you in school in the first place. The average employee gets taxed 40%, small business owner gets taked 60%, not very attractive when 80% of the population doesn't like their job. A business owner gets taxed only 20%, an investor gets taxed 0%.
Most people don't know these things but most people went to school, and I feel sorry for the people that are going to live paycheck to paycheck working for that promotion so that they can spend more money and still live paycheck to paycheck and be unhappy working as an employee. These people could have started their own thing, but school doesn't teach you that, school teaches you to become an employee.
