I think a lot still needs to be done, and can be done, to educate the public about basic economic principles. I hope to do my part to help by creating quality online resources for this in the near future.
To give a more concrete example of what worries me: It should be obvious to everyone here that an idea like "minimum guaranteed income" is a very dangerous idea. Yes, there are credible economists that believe these things are a good idea (and it might even be a correct idea) but they believe this for very different, and much better informed reasons than the arguments being bandied about in this forum. Many of the arguments made here in favor of "minimum guaranteed income" are wrong and even the Economists who support these things would agree that your arguments are wrong.
Anyway, as I said, I hope to create some online resources soon that will show more clearly what the difficulty is with these types of ideas.
EDIT: For those asking me what the precise problem is with "minimum guaranteed income", I can't give you a satisfying answer, because I can only make an obvious qualitative argument right now (i.e. people will stop taking minimum wage jobs if they can get the same income without working, or by working in some less efficient fashion prescribed by a "guaranteed minimum income" scheme.) What needs to be done is to bring this discussion into the realm of mathematical "economic models" so we can quantify these things and ask questions like "How much will a guaranteed income help people?" and "How much will poor people be hurt indirectly by putting such a scheme in place?" (and of course ask additional meta questions such as "Is this model appropriate?") But these types of questions can't be addressed in an HN thread and require a more in depth treatment.
