Something that can make this world economically better is the money education. Most people don't take money education seriously. They think that what they are doing with their money is the best possible option. If your money is not earning passively, you can never be rich. The problem is that people don't manage their money smartly and that differentiate a poor from rich.

I would like to quote a line from the book "Rich Dad Poor Dad"

""Everything the working class has been told to do, the rich do not do.""

I know that money management is a small part of a better economy. But it definitely is a gear.
