Math isn't worth it if you aren't getting a PhD in it. Even if you are, applied is where the big bucks are, and you can get into that from an "easier" major. Pure is good if (IF) you're genius tier with great luck that your professors' interest align with your inborn ability or whateverthefuck other esoteric shit you need to actually be meaningfully successful in a field to the point of getting tenure somewhere worthwhile. All the while you need to work your ass to the point where the type of stuff most grad students struggle with feels like the multiplication table. Only then can you maybe begin to get to the point where you can actually contribute something meaningful. If you're in it for the money, become a codemonkey somewhere or some shit, math is pure masochism. Math major into econ PhD is also big bucks and relatively comfy. Have a classmate doing this and he worked for a summer in some stock trading garbage and got 200k out of it.
