I feel sad for you that you think people cannot create something from nothing.

So if you gain something, does that means somebody else needs to lose? Is that how people justify stealing or scamming? Or is that how they cope with their envy that rich people must be stealing or scamming.

I once knew a person that had this theory about happiness. If someone is happy, someone else needs to be sad.

I feel sad for anyone who has this mindset. It's way nicer on our side, where we do win-win deals, and know to be happy, the people around us need to be happy.
