Compliance does not generate any revenue of their own. They support revenue generators to make sure they dont fk up on the regulatory things and end up losing all the revenue due to heavy fines. It is not exactly bad to be in compliance, it is merely societal pressures to always aim for the best and it is thus just general advice to always aim to be in the depts that are the ones responsible and contribute greatest to the growth of the company so that you can make the best career and money out of it. But if you are happy with doing compliance work, then so be it too. As long as you are happy and contented, then that is great as well.
