There are so many angles for getting/keeping money. Legitimate investments and arrangements like stocks, bonds, options, futures, derivatives, commodities, arbitrage; real estate, commercial real estate, REITs; savings accounts, IRAs, Roth IRAs, HSAs, 401Ks, 403Bs, 529s; I could fill up this page with various financial instruments intended for wealth maximization. And that’s not a bad thing. I’ve spent considerable time and effort learning about these instruments and employing them for my own ends. They have their place.
There are also schemes, cheats, and tricks. These mostly involve fooling customers, cheating on taxes, skipping out on debt, etc. These are for losers. You can’t prosper long term by cheating.
Over the long term, your economic reward will likely be dominated by one component: the value that you deliver to others. (There are exceptions – Gandhi, Mother Teresa, etc.) Don’t waste your energy looking for a shortcut. Stop trying to work the system. If you want more, earn more. Focus on maximizing the value you provide to others and the money will follow.
