"Really? I seem to remember learning in micro that "minimum wage causes unemployment" and then years later finding out what that model was based on, i.e. you must assume a healthy market clearing process exists, wages aren't sticky, labor is liquid, perfect information, no market power, etc."
That sounds macro. There's a reason I distinguish between macro and micro. Macro I simply don't believe in due to it being anti-inductive (google it if you like).
I've actually seen micro reformulated into physics via thermodynamics, and seen it used to model ecosystems. It's far more fundamental than humanity itself.
Microecon is like thermodynamics, in that crazy applications of it can cause various effects that may initially seem to violate the theory, but are really just complication macro systems that produce seemingly-micro-defying results, like how a refrigerator is not a violation of thermodynamics. If you don't believe in microecon, you are not justified in then becoming a Marxist or declaring that governments are the solution or whatever other agenda you may have... you are declaring that we are profoundly ignorant and have no useful economic model whatsoever, and can claim nothing. If you can't believe in a free trade between two agents producing a net gain for both without political ideas intruding and immediately trying to reformulate this micro case in politically-loaded macro terms, you are not capable of thinking about economics at all. You're only thinking politics. (And if you read this as me trying to sneak a macro model in on you, you're still having trouble. This is basic stuff like the basics of how atomic bonds form; what glorious life forms may form out of those are wildly varied, and very difficult to derive just from a description of how molecules bond.)
