One consequence is an immense concentration of political power in the hands of 85 people.
Yes, brilliant observation. This is the real 'danger'.
........That capitalism, in it's distorted/corrupted form that we currently have, places political power in the hands of the rich.
Is a pure capitalist model, that would not (necessarily) happen.
There is some truth in George-Ananda's comment, but it's also wildly naive and western-centric. Do you think the money of these billionaires and oligarchs are working wonders in Africa? ... in rural India? ..... even the run down, depressed suburbs of Northern England where 500 people apply for a single part time job on the checkouts in a supermarket?
The system will collapse ... no doubt. History proves it. Corrupted free market systems are why we HAD communism (for a while) in the first place.
The only question is, when the
tipping point will come, and what it will look like.
