In addition to my already present uh, biographies...
I would nitpick this actual meme on one point:
Broadly, monopolies and colluding oligopolies do not collude to artificially increase demand.
They collude to artificially increase prices, and that artificially high chunk of prices is also called a monopolist rent.
...
Monopolists grow till there are no alternatives to them, often by first offering a price discount as compared to other competitors...
... then, when they have driven their competition out of business, or just purchased them...
Then they raise prices to the max the consumer can bare.
...
Monopolists notably maximize their own profit often to the point that it actually reduces overall demand.
They can do this because they still have enough people who now just have no alternative, and they can extract so much monopolist remt... maybe we'd call that greedflation in more modern lingo... that they don't care if they lose a few customers, the astounding margins more than make up for it.
(until the entire system collapses sometime later, because OOPS, turns out everyone was going into debt and gambling on wildass longshot investments to be be able to pay those higher prices.)
(but of course then the monopolist just lays off employees to reduce overhead, and hey, now you understand why and how recessions and depressions happen, and why capitalism is fundamentally inequitable and unstable!)
