I have a younger relative, making a very very comfortable living, who has taken on the developing the software for a number of small companies as a solo dev, each pay him for features and a pretty decent (non software decent) annual wage for ongoing maintenance. He makes no secret that he has multiple clients, there's no duplicity, and he gets to have a flexible life where he travels when he wants and exercises a couple of hours a day. Every client he's ever picked up has kept him on. He's got the full skill set to be able to be sales negotiator, designer, tester, dev. It may be that many of us don't and are more valuable, and will be paid more, in a team that blurs our deficiencies.
