Well, you mention that you sold Matasano, but that kind of sidesteps that you'd be screwed if it didn't happen. It's not tech workers vs retail clerks so much as financial windfall vs having a regular 9-5.
The credit system just sucks. It's a historical accident. But it's also not really realistic to say "In some cases you can get away with not worrying about your credit score if you're a tech worker."
I'm not arguing that the credit system doesn't suck. It sucks so much that I haven't had any meaningful contact with it for 20 years. For most of that time, the overwhelming majority of which I spent financially insecure (and a parent, to boot), my disengagement from credit has ended up feeling like a blessing. I genuinely do not understand why people get credit cards.
As for "windfall vs. 9-5", I spent ~20 years in the latter category, a category which I'm not unlikely to end up in again, and I simply don't agree with you.
Maybe another way to put it is this: for all the problems you've had with personal finances, I assert that acquiring revolving credit is a good solution to none of them.
Finally: since litigating this further is inevitably going to involve getting into pretty squicky financial details and debates over personal financial decision-making, I'm going to stop here. Since I think you'll probably disagree with me, I want to be clear that I expect and will read any rebuttal to this that you write, but I'm not going to continue the debate.
It solves getting your kids through college. That's one of the other pain points. The quality of life difference is massive if you have to work full time and also go to college full time.
It would be delightful to find an answer to some of the problems of bad credit. But it kind of matters.
