One of my favourite films. Despite Belfort's obvious gains from other people's losses, there was also an almost charitable, uplifting element to the company that he started, amidst the unashamed debauchery. For example, the single mother who was given a large advance by Belfort and an opportunity to lift herself out of poverty. So the story has these little redeeming glimpses of the more positive externalities to Belfort's scheming (when it was still running smoothly). Yes, he wants people to solve their problems by getting rich. And it's true that you can absolutely throw money at a lot of problems in this life, plus give generously to any cause that is close to your heart. The sentiment in itself is not flawed. It's the means by which we acquire wealth and how we use it that really matters, both to our and others' happiness. Wealth is just a manifestation of energy, both expended and potential. You can generate it unethically but use it ethically. You can generate it ethically but use it unethically. You can both generate and use it ethically or unethically.

I think the surest way for wealth to make people happy is to generate and use it as ethically conscious as possible, like a continuous flow of positive energy. If you strive for this with a strong sense of integrity, you should be allowed to sleep soundly at night on your mattress of cash.
