I think there's a whole spectrum, but most of the active posters here fall on the side of having more than what I see in real life. In my clubs and circles the most expensive we have is a 70-200 f/2.8 and less than 2% have something like that. I've only seen one 'big white' in person in 10 years of photography which often takes me around other photographers. Having even a full frame puts you in the top 10%. I know lots of very active photographers who use a kit zoom, wide-range zoom, or a few simple and inexpensive primes.
In real life I have seen one 'big white' in person, a 300 f/2.8. It was beat up and not in the best shape, hood held on by duct tape and the like. The user was a professional sports photographer. Many photographers I know may be 'addicts' of a different type, addicted to the act of photography itself or that which comes with it. There can be a dark side there too, but it's generally not that bad.
I do agree with Dan on most points, while minimalism can be a useful concept when it comes to logistics, I don't try to use it to bring about creativity or anything like that. I try to stay within balance, buying something new only when I feel like there are clear and compelling times when I would have benefit from it as part of my current shooting experience. While I may have more than the average person, I don't have anywhere near as much as the average person here.
