Not the person you asked, but... Yes. If you do things right and get a little lucky, you can make much more as a freelancer or consultant.
In the short term, but is it reproducible for the long term? How does the 10, 20, 30 year outlook look like? From my vantage point, it seems that most freelancers have pretty short shelf life.
