I used to know a guy who was incredibly competitive with me. Anything I did or bought, he had to buy.
The problem: He made close to minimum wage, and I was making tech bubble money ($150/hour 40-60 hours a week).
So, for example, I bought a laser printer (which was $1000 in the early 2000's). So he bought a printer just long enough to show it off to all of our mutual friends, and then returned it. He did that with a lot of stuff. I found it tacky and trashy.And really weirdly obsessive about trying to have all the same shit that I had.
It wasn't like he needed any of that stuff and was desperate. It was all fake conspicuous consumption for the sake of raising his estimation in the eyes of our mutual friends.
