Clearly productive investment is better, that last point is a bit tongue in cheek, but there’s at least some truth to it. The least productive use I could think of would be buying bitcoin, which is basically just funding turning electricity into heat.

Someone gives up most of their life to make the investor even richer. In exchange they get barely enough to eat and put a roof over their head (in some cases not even that). What a fair deal, praise the investor!
