I've been in the field for a nearly two decades now, and it's highly recommendable. There's a game-like element that appeals to a certain type of person.

As for doing good in the world, there's an awful lot of businesses that really only contribute via tax. They do something where the entire benefit, sometimes more, is captured between the business and its customers.

But to say it specifically, you need market makers, because if they weren't there you'd have to wait a long time for someone with the opposite intention to you to show up, and that has a huge cost. And keep in mind MMs are only one part of the capital apparatus that we need in the world. This isn't just fluff, I literally had a friend phone me last week looking for money for his African startup that has had to turn down business for lack of capital.

The how of it is a long story as well, but quite an interesting one that spans a number of fields. Coding, economics, finance, and so on.
