How much of billionaires’ wealth might have de facto already been redistributed?

Sir, John Gapper writes interestingly, from the perspective of how these are designed, about “public art museums funded by billionaires”. He concludes in that, as so many follow the same principles; it is beginning to have similitudes to a franchise. “Billionaires are franchising the art museum” August 9.

Currently in the political market, way too often we hear offers phrased in the simplistic terms of: “Let’s take it from the filthy-rich and give it to the poor and, Puff! all odious inequality will have disappeared.”

In order to stop the creation of those false expectations, which at the end only leads to frustrations and the enrichment of the of the redistribution and/or polarization profiteers, by increasing the value of their franchises, there is a real societal need for much more information. 

Like, what wealth to be redistributed are we talking about? How much might billionaires have already de facto redistributed their Main-street purchasing capacity wealth, by demanding and buying assets that no one else but them would be demanding, at least not at those ridiculously high prices?

Not long ago, someone really wealthy, by means of a sort of voluntary tax, froze US$ 450 million of real purchasing power on a wall, by acquiring Leonardo da Vinci’s Salvator Mundi. Sir, I ask, how do you redistribute that painting without perhaps serious unexpected consequences? Cutting it in thousands of small-certified pieces, and selling these in the market for much more than US$ 450 million?
