This theory is very reliable!

First, let's clarify a concept: if we compare our world to a game, making money is like earning contribution points. The more you contribute to this world, the more money you earn. Just like stock trading, you might not be laboring, but you can still make money. What kind of money are you making? You're making money that supports good companies. You give money to good companies, whether to help them expand or to enhance their risk resistance. They can contribute to the public, and by supporting them, you are also contributing. Therefore, contributing to humanity doesn't necessarily require labor; supporting the right things is also a contribution.
