alt Hacker News> The math doesn't math for someone on the other extreme end of the spectrum who has zero savings or investments and obtains all his income from labor: To him, a N% wealth tax = 0% income tax for all N. Those with -some- savings are somewhere in the middle.
Productivity comes from labor AND assets though. You need the farmer and the tractor. Why would we create a tax system that encourages people to divorce themselves from having a stake in the means of production?

The current system without wealth taxes already largely divorces labor from equity stake. Unless you're one of the relatively few tech or office workers who get equity compensation or have a large savings rate, you currently don't have much of a stake in any means of production.
Regular people have less and less savings to buy "stakes in the means of production". Capital is getting more and more concentrated in fewer and fewer hands: the top 10% of the country owns almost 80% of it all. Wealth needs to be taxed and redistributed.

This is exactly why economic models broadly show that taxing capital assets makes workers worse off in the long run. An abundance of capital means that workers will be more productive on the margin, so their wage will be higher. This extends to the capital-income taxation involved in income taxes: pure labor taxes or consumption taxes are inherently more efficient. There are countervailing effects (taxing capital income works as an effective way of indirectly taxing the unearned value of resource-like assets, or of idiosyncratic skills that happen to correlate with holding more capital-like assets) but they can only roughly justify the current income tax arrangement, not some extra tax on assets.
