an out-of-the-box way wealth taxation might yield a recurring flow is to let it compound in a sovereign wealth fund. compound growth of a sovereign wealth fund is fiscally similar to increasing capital taxes year after year, but with no new taxes enacted. www.interfluidity.com/v2/6987.html
Text: A sovereign - er, social — wealth fund is a taxation machine. It is an automatic taxation monster. It takes the miracle of compound growth that capitalists are always on about and turns it into a miracle of compound taxation, effectively taxing wealthier cohorts (those who would otherwise own the SWF assets) an ever increasing share of income year after year without requiring any new legislation, and with minimal distortion of investment behavior. To see how this works, let's imagine that we want to simulate the flows of an SWF+UBD. We'll imagine a very simple scenario. Let's define a "notional" SWF. The SWF is going to be financed by a tax enacted just once, which will yield $1T in Year 0. The tax take will grow with nominal GDP, which we will model as growing at 5% annually. Beginning at the end of Year 1, the SWF will make payouts. For simplicity, we will base payouts and returns on the end-of-prior-year balance. That is, we are conservatively assuming that the taxes we collect within a year are unavailable until the year following. We will assume a constant rate of investment return of 8% per year. Echoing Bruenig's proposal, we will have the SWF payout 4% of the prior year balance each year. However, instead of actually forming the SWF, let's say that the government were to decide that there's no need to intervene in the miraculous private sector with actual state ownership, that the assets can remain, um, efficiently managed in private hands but the government will simply use the tax system to reproduce the flows an SWF would generate… [truncated, see the linked piece]
