> The fiscal myth is increasingly unpopular on the left (and even starting to fall out of favor in the center-left, hence the rise of MMT). So, no, largely and increasingly leftists don’t think this way even if they mistake intent for effect.
That can only be a good thing. I don't move in leftist circles much (or really any political circles) so sadly I'm not up-to-date on the current thinking.
> The “Law of Unintended Consequences”, while it relates to a real phenomenon, is both dramatically overstated and not meaningful as a rebuttal of any particular idea. If you want to rebut the argument that a specific proposal to increase high end taxes (not the generic concept which you then massage into a form most suitable for rebuttal) will not actually increase net revenues, you need a specific argument from the elements of the proposal, not a generic handwave in the direction of “sometimes changing the rules does something you didn’t expect”. Since, I mean, that can just as easily mean that it succeeds beyond expectations than that it fails, when the effect manifests at all.
It wasn't intended as a rebuttal, but as a call to action to engage in systems thinking. Basically, under a reductive model of causality it's easy to make the mistake of thinking that well-intentioned policies are all that's necessary. Instead, if you're looking to enact a specific effect you need to consider both the effect you're trying to counteract (a too-high power differential) and the response to the policy you enact (in my loose example, the policy just being included in the equation already in use by lawyers, accountants, wealth managers etc that the very-wealthy already employ).
I highlight this because I'm both interested in systems theory and in building a better society (as, I suspect, most people are) and one of the main applications of systems theory is how to get the outcome you desire when trying to change a complex system. The way to do this is usually not obvious - because if the obvious solution worked, the problem would be easily solved.
I'm not trying to dismiss the intent behind the suggested reform.
