In case you didn't gather, I consider the "stimulus" aspect (and the related ideas) to be the major problem with those two economic views. If the answer to the question of whether stimulus is a good idea is "No" - a question neither school of economics truly addresses, assuming the answer to be "Yes" - and both schools of economics fall apart.
Yes, I understand that. What I don't understand is how you get from "Gunnar approves of economic stimulus and I don't" to "Gunnar is engaging in wishful thinking". Nor for that matter why you pick out Keynesian and Reaganite economics in particular, since so far as I can tell liking the idea of economic stimulus is pretty much universal. (Though clearly you don't share it.)
This thread is for asking any questions that might seem obvious, tangential, silly or what-have-you. Don't be shy, everyone has holes in their knowledge, though the fewer and the smaller we can make them, the better.
Please be respectful of other people's admitting ignorance and don't mock them for it, as they're doing a noble thing.
To any future monthly posters of SQ threads, please remember to add the "stupid_questions" tag.
