I think thats a really blunt statement. It makes no sense, and its very judgemental. Unless your saying all guys in rings you think less of, which is just as bad.
The original poster asked what we thought and that's what I think. You don't have to agree. Sure, it's judgmental -- I'm OK with that. We all make judgements in life.
I think class rings are tacky and lowbrow, especially if the person's been out of school for a while. If someone hasn't gotten sick of that ring and tucked it away in a forgotten drawer within a year then I think they've missed a memo somewhere along the line and I'm going to think less of them because of it.
Higher education, even postgrad work, is little more than the preamble to your life. While it may require tremendous effort, let's not confuse it with actual productive accomplishments.
Build things. Create. Achieve. Education is just training so that you might have success doing those things in the real world. To focus on the training and not the doing seems misguided to me.
