This comes from a report McKinsey released in 2021, in particular this chart showing just how much value is taken up by land, other non-produced natural resources, and intangibles (which includes but isn’t solely limited to patents/copyrights).

Georgists across history have proposed to tax/reform these things. This isn’t to say that, with something like land for example, we’ll get 35% of global net worth in real assets as revenue, only the yearly amount paid for these resources will be paid forward to society (assuming we tax them, Georgists have a variety of proposals for something like patents/copyrights). This also isn’t to say this is the end of Georgism’s impact, we have targeted more finite (i.e. non-replicable) assets beyond the ones listed, and we also know that a lot of financial assets are tied to things like land as well.

But, about 40% of global real assets is certainly a good start.
