I think you're spot on with this.
This seems to be the public establishment of a neo-feudalism, where the new barons are the megacorp capitalists, who can afford to strategize long-term and implement land grabs, while lobbying with governments to strenghthen their stranglehold on the people by capturing natural resources. Capitalist piracy, in a sense.
Now, I'm not a (neo-) Marxist in the strict sense, but this is too much in line with the Marxist understanding of the state as an institution that looks out for the interests of (big) property owners, rather than those of the people.
Fast forward a couple of decades, and we can project with some certainty an outright voiding the social contract that understands the state as a neutral institution that cares for the interest of the people, and reverting to such feudal-esque configurations.
And, for the record, no, I don't believe for one second that playing it the capitalist way and buying shares in megacorps has any possibility of having a positive counter-balancing effect. It'd be more like buying shares in slaveships, and partaking of the profits of the trade.
I agree that most people can't, and we need to do something to ward off a populist uprising
Now where does the average person find the initial capital, such that they can enter the game of capitalism..
The average person gets the initial capital to enter the game of capitalism by living like a poor person and banking the difference. That's how it works: this "capital" that earns a return is simply the difference between what people earn and what they consume. If you get a positive return on it you might eventually start being able to earn like a rich person and live like an average person.
But that's not enough Lords!
Strong, "let them eat cake" energy with this one.
