how to make money from competing?

[omgisabel]

hello! i currently have a lot of grand champions++ and master champions+++ competing in dressage, hunters, driven dressage, hunters, western pleasure, western trail, and working ranch. it seems theres not a lot of prize money to be made in these disciplines though they seem fairly popular. when i was playing a few years ago, dressage was the most popular discipline and was how you made money. what discipline is currently making the most money from prizes? thank you
