What frustrates me about this whole argument over wealth taxes is that the arguments aren't grounded in facts. The reality is that we "pay" for inequality with reduced productivity. A great example of this is "single family home neighborhoods" in urban areas. They have no societal benefit, they are essentially subsidized land use patterns for the well off, and it makes it harder for less well of folks to move to area…
You say this, yet you don't provide a single citation for any of your arguments.
> There is a very strong case that one reason for sluggish economic growth is the concentration of assets and wealth in so few hands, and the continuing stagnation/decline in wealth/living standards/etc of bottom 40% of the US when measured in things like "healthcare", "education" etc. A redistributive wealth tax that was well structured could be a huge boon to GDP growth.
This seems plausible, but not self-evident. Give us evidence.
