In my various readings of econoblogs, I ran into a quote on one of the problems with the American economic downturn was people who consumed, but didn't invest. This idea wasn't explored enough (and as I can't even remember where I read it, I suppose it could have done with more detail), but it got me thinking about investing versus consuming.
I want to explore the difference – and it's relevance to your career as a progeek and profan.
