bkshopr,
You are right that there is no right of wrong answer here but nonetheless, being high school educated or with a terminal degree does is not the finality to how much a person makes (though most stats might say otherwise). Yet the question here is how you use what you learn. I am an educator and one thing I see that most students suffer is making the link between big picture issues to micro level day to day living. I see how most parents and teachers screw the kids up by narrowing their comprehension and application capabilities by guiding them to super specialized fields or not thinking out of the box. Take computer software, my adage is if you learn one software you learn it all. Why? because all the shortkeys are the same. Understanding fundamentals and making the link btw for eg how a bicycle works can translate to a automobile, pully systems etc. History is so crucial that you can draw a line on a specific year btw economics, social and political events and you can draw parallels everywhere. Your expertise in fengshui translates to architecture, chinese culture, ecology and environmental sciences. The possibilities are endless.
It goes back to the the basic nature of parents dumbing things down for kids when they are young. Stop telling telling babies that all flying winged objects are birds or planes, tell them its a crow or a boeing 777, they have so much more learning capacity than we give them credit for. I personally believe that I use everything I learn at my work place, if I don't, I will find a way to use it.
