Past being a millionaire or so, making money is a clicker game. It's something you do just for the fun of seeing number go up. And just like a clicker game, past a certain point you're no longer making the money through your own efforts, but by acquiring assets that can make the money for you (like buying the grandmas that bake cookies for you, etc.), so the game becomes determining the right mix of assets that let you acquire more, that you can then plow into more assets for even bigger growth.

The super rich aren't making more money because they think more money will buy them correspondingly more happiness. It's a game to them played at massive real-world scales.

Any ideas beyond real estate?
