But because my anecdotes are just as good as anyone else's, the place where I started my career has plenty of 20-30 yr veterans in their IT department, and they are a warehouse company with an IT staff of over 200 people but their tech doesn't directly make them any money at all.

If you're limiting yourself to tiny tech companies, you're missing out on a lot. Maybe company size and products sold aren't necessarily a good indicator of your career success...?
