Perhaps. In my case, I was part of that socioeconomic class from birth to 16, but from 16-20 I was homeless, and from 20-right now I was very poor, far beneath the poverty line in the states. I kept that sense of fascination, and I've met tons of people who are dirt poor, and have been dirt poor their entire lives, who have that sense of fascination. I've met fewer people with it in the middle and upper classes. That's not to say that there aren't a whole bunch of very poor people who lack it. If I had to honestly guess, I'd say that it's somewhat related to intelligence, and how many different ideas someone gets exposed to while they're young, and that the percentage of folks who are fascinated by the world is approximately the same throughout classes, and that I just haven't met enough middle to upper class people in my adult life to know yet. I really, don't think that it's a luxury of class. It may get affected by class, but I don't think that the effect is as big as you suppose.
