As particular firms compete to drive down their costs (espcially of labour) by roboticizing there will be fewer and fewer workers earning wages to buy the stuff that is made. Firms will be competing to push down wages and create less workers for the individual firms, but systematically they will be destroying demand for all the goods of all the firms. If there is one rich person for every poor person, that rich person will never buy the volumes of middle class goods that 99 workers would've bought, like couches, basic cars, food, etc. So as wages become more and more inequal between the few workers who are still needed (with low wages because of high competition and supply of workers), industry produces less of teh stuff we need, and those prices rise, while more and more investment competes in the production of luxury goods. This basic dynamic is why, despite the green revolution in agriculture of the 1970s, where we hugely increased food production globally, 1/7th of the world still starves today like it did before the green revolution.  In capitalism the ratio of monetary distribution remains stagnant. Stagnant to a certain ratio of workers needed to produce to sell to other workers, so it remains unprofitable to distribute even the surplus food, which rots or is dumped to destroy less efficient producers (also destroying less developed economies' agriculture).

Free market capitalism is a ridiculous concept, even Hayek agreed that markets tend towards monopoly and oligopoly... We know only 35 firms/share holders control the majority of industry the world over. Look at bitcoin, it's already %85 controlled by just a handful of parties, and it's a totally new, "free market". Traditionally, "libertarians" held that the state was needed to break up monopolies, which is circular because, of course, the oligopolies and monopolies become the state and vice versa.

Any monopoly holder in the economy, without a state in existence would form a private army to enforce his claim to his monopoly despite people starving and children dying from poverty. The operation and management of that private army would quickly be the bureaucracy that could extract tribute, extortion, (taxes). Force isn't just weapons, it's the protocol and especially the communications of the protocol for tactical strategy and initiative in deploying units. Force is also the maintenance of your units in the long down time between deployments of force.

In capitalism where wealth accrues to wealth (when you have large reserves of money to invest you can make more money), we have inheritance, and well over %90 of the wealthy are rich through inheritance. That is just a fact, it seems like we only hear about all the "self-made" wealthy because no one touts the fact that they're rich only because of the birth lottery.

Everyone is sticking to communism as centrally coordinated by a state, where we're all here because of peer-to-peer technology! Economic planning within a community of relative equals isn't possible because of the internet?!! THINK for a second! MY GOSH!

An MIT physicist and economist has devised the first complete METHODOLOGY/PROTOCOL for de-centralized economics. It's called Participatory Economics and his name is Michael Albert. Study it, it is really the only economic methodology probably ever created.
