Haha, well, that's why I said, "a little tempted..."
And it would need to be an almost mythical sort of job offer: "a relative guarantee of job security". That really doesn't exist these days.
Every year of self employment gets a little better, but I know there'll be a cap at some point on what I can make as a solo operator. Considering all of the things that come out-of-pocket for us, the actual equivalent salaried income wouldn't be close to $100k/yr. For some guys, maybe it is. We all have different things going on in our lives, and factors in our personality and physical makeup that affect what we are capable of.
But for some of those same reasons, a full time position working for someone else probably wouldn't be a good fit for me, either. The bottom line for me isn't really about the total income. It's about the level of effort, stress, and preoccupation required to make a living, vs. the time leftover to have a life...
