I do have a family to support; my wife stays home full-time too, and I'm the only one who works. We meticulously save up money so I can quit my job if I no longer like it. My wife and I prioritize convenience and a relaxed home environment over all other factors. We are prepared to live on /very/ little, and if I find in the future that I really don't like software engineering, I have been working on learning to build fine furniture (And have been somewhat successful!), so that remains an option for supplementing income.

After working several jobs I really hated, we've decided to never become beholden to a company again. People pay you money if you do work that helps them. If you get this, then making money is straightforwards enough, and you don't need a whole lot to get by.

The only place where this falls apart is medical costs. However, in my opinion, the fact that you can go bankrupt from medical costs is more an indictment of America's healthcare system and lack of universal health insurance, than it is a valid critique of my philosophy.
