Earlier quoted context omitted.
The problem literally is that many people don't have an adequate share of the GDP. The footnote proposes to tax capital the same as labor. An interesting thing about Bill Gates is what a tiny sliver of GDP he managed to capture over almost 40 years. Something like $0.1 trillion out of several hundred trillion dollars.
Caveats: GDP is no way to calculate wealth, and comparing the total GDP to any one person's wealth is pretty useless. Let's say the total GDP over the last 40 years was 300 trillion dollars. Also, let's say Bill Gates's wealth is 100 billion dollars (for ease of calculation). 100B / 300T = 0.003 = .3% of 40 years of GDP Let's say that the average population of the US during that 40 year period was 170M[0]. 170M * 40…
But that was the point of my post, to compare the captured wealth to consumption. People always talk about how the wealthy are screwing the rest of us over and everything would be great if they weren't taking so much, but it turns out that consumption is also a huge portion of the economy. Total wealth in the US is on the order of $100 trillion (this includes all housing and so on). Consumption of several trillion dollars a year adds up to that pretty quick and seizing it all and turning it into circuses isn't going to go very far.
Which isn't to say I am against programs that result in wealth transfer, it just pays to try to look at things clearly.
