A proxy for product (as in GDP) is Income.

The way you get that income into a shareable pot is via Tax.

So the best way to do this is still good old "Income Tax."

Unfortunately those with the most income don't like to have it taxed. And national policy tends to correlate pretty reliably with whatever those people want. Anything akin to what he's suggesting would help even things out, but that is precisely why they won't permit it. The only way for the masses to assert themselves is through their brute numbers.
