Some insight: if you don't engauge in common activities, your borometer of what is interesting or useful to the average person drifts, and fast. That is just something I learned from being somewhat similar in my persuits. Your income based assumptions also, are very different from my experince. The middle class has a grind, that the lower and upper classes are less bound to. I find upper-middle class friends to have the least free time, and the most harried lifestyle. I find a good gauge of having free time to research or recreate is reading frequency. Ymmv.
