Yeah, I can't understand the widespread ignorance of/indifference to micro either. It's like people either think it's less important (because of the name) or that it only applies to people running manufacturing or retail businesses. Macroeconomics is seriously incomplete, so when it fails to predict the future well people dismiss economics as a whole, not realizing how fantastically useful and illuminating micro is. Admittedly micro suffers from not having a good theory of oligopoly, but I venture to suggest that that's a bit like the 3-body problem.
For philosophical types, I recommend 'New Ideas from Dead Economists' by Todd Buckholz. If you just want to get going with the math, I like the Barrons Business Review book on Economics by Peter Eisen. You should be able to find either of these used for a few bucks.
