Maybe I'm reading too much into it. In any case, sometimes I'm a hacker, sometimes I'm an engineer...but I get really annoyed when people think I should act a certain way because of my current job title.
About the "feed my family" - when you're on a forum like this one where so many of the people are young single guys sacrificing all to follow the billionaire/world domination dream, it's not sexy to say you make decent money fixing bugs for an app that helps gazillion dollar companies make more money. I get to do some cool stuff (that I probably wouldn't be doing in my own projects) and facing different constraints, and I do it while doing a good job providing for my wife and kids. No shame in it at all, it's just atypical for Hacker News.
I was right there with you on the Ikea metaphor, and thought you were doing a great job of defending the creativity of the lowly engineer, but then you seemed to go apologetic at the end. I hope you don't think I'm arrogant, if I suggest that you cut that bit out. ;-)
"Right now I'm a software engineer (really, it says it on my business card!) and it has been good to me. I get unusual technical challenges that I wouldn't have come across in my own projects, and unlike the "friend's couch and ramen" startup life, I can feeds myself and my family and live comfortably."
