You would of course also say that sitting on the front porch sipping lemonade and conversing with friends is not productive time. You are an idiot.
I assume your constructive criticism above is just part of your largesse.
However, I am not sure what your point is about "constructive time"? I am not concerned about whether anyone is using their time constructively.
I still do believe that youth today, and for decades in the past, reflected two fairly different demographics, those in private school and those in public school. Where I am, the parochial school system constitutes the largest private school system, and their students tend to be the youth that pursue goals after graduation. It might correlate with the goals of the parents, or the belief that parochial schools are better at teaching the 3-R's? Regardless, I do not generalize about the youth of today, since some of them are goal oriented, willing to work hard for goals, and might just be very realistic in a society that has seen many union jobs go the way of the dodo bird.
And, it has been my observation that many an entrepreneur needed to be an entrepreneur, since they would not fit in well into an organization where one had to have a hierarchal table-of-organization, with everyone having a boss, and needing to "fit" into a team, where one took orders. Based on my experience, I value the ability to work in an organization, where one takes orders from bosses, and understands the concept of being a subordinate. Perhaps, my military experience taught me that. Anyway, that quality to fit into an organization may be the keystone to maintaining civilization, not the ability to be an entrepreneur and not have a boss. Or, rather be "the" boss oneself?
