This is not going to be popular, but this is one accountant talking to another about professionalism. You will never be happy in accounting if you keep comparing your clients' income to your own income. I've worked for many high-wealth clients who make exponentially more than I ever have made or ever will make. I just simply don't know enough about them to make a judgment about whether this disparity is "fair." In my experience, it is the client's character that matters most. I'm perfectly happy to work for or with those people as long as they're nice. If they're total jerks, then I'll hand the work over to someone else or withdraw from the client. And if you think you deserve more than you're currently earning, then plan a way to ensure that you can earn more -- take classes, get certifications, get an MBA, etc. Take the frustration you're currently feeling and channel it toward improving your own lot in life.

Yet another example of the ever-widening gap between the "haves" and the "have-nots".
