So what? You're not doing it for a job, are you? You were implying that market income should be more valued in society than learning and that education should be measured in terms of income. That kind of thinking is disturbing, IMO.
Just using the one example of many... Trades are a form of learning, a practical education, and a very rewarding and utility laden thing to get in to. My time in the trades has left me aware of and interested in the methods and applications of an incredibly diverse and fast moving construction industry. My home is my playground, where I can change rooms, mix and match, imagine it as I like, and then make it happen with the literally thousands of little tricks that I have learned from extremely intelligent, capable, and resourceful tradesmen I have spent time essentially apprenticing under. I can tell you what kinds of paint do what, how to make that wall with a ding in it perfect, how to properly build a deck in whatever shape I want, I can... Well, sufficed to say, I have been "educated" to do many things I would leave college totally ignorant of. I'm empowered, by this education, in a way a lot of people aren't, and really don't appreciate.
You mistake my assertion as "MAKING THE MONEY IS ALL THAT MATTERS!"... Rather, I think college educations are valued, disproportionatly, above and beyond what you can learn in other areas, in other ways. A person with a formal education is learned in many ways, and ignorant in others. I think it's time that, as a culture, we place a bit more value on the knowledge of the master tradesmen, perhaps even to the point where we honour that knowledge alongside that of a professor. Both are masters, in a sense, with tremendous knowledge to impart - but I don't see many people dreaming of being a carpenter compared to dreaming of studying Romantic poetry. The thing is, I believe a lot of people who *think* they want to study Romantic poetry, who bought the myth of the grandness of the college education, might actually find learning to craft a house might be more rewarding and engaging.
