I doubt money supply has much to do with the issue at hand, since we're looking at the real world and money is just a tool for managing it.

I think you're correct in that everything is very expensive, possibly close to the most expensive it can be. Salaries paid are essentially just what is enough to keep yourself alive nowadays, often not even enough to keep yourself in decent mental health. I doubt your average worker is capable of purchasing everything they create in a month with their monthly salary.

It's certainly not the first time this has been observed either. Let me give you a classic criticism. Take the old but reliable labour theory of value. We ignore price fluctuations for this analysis because they are considered nothing but representative of true value – a method of making trade easier. Work is what people value, specifically the time used for labour. Creating something in one minute gives it one minute of value, it would be more valuable if it took more effort to create. For the purposes of markets, it's also obvious that what matters to us is not the individual value per se but the socially necessary labour time, the average value taken to create something. Therefore a man who creates a spoon in one minute and a man who creates one in 20 will make an equally valuable object in the societal context. Creating an object from materials will have the value of those materials plus the value you create through your work, so $2 bread from $1 wheat will have $1 of additional work done by the baker.

With this in mind, let's investigate farming. A farmer works land, they create $1 worth of wheat and sell it. That $1 is the full reimbursement for their work and if they want to buy their wheat back they will pay that $1 for it.

Adding in an agricultural conglomerate, lets say that a bunch of farmers work the land of this conglomerate as employees. As a large oversimplification, we once again say that a farmer creates $1 worth of wheat for the company. The company sells it and returns to pay the farmer a salary: ¢80. The ¢20 missing is the profit of the company and it has to be larger than zero for the company to keep existing at all, profit being their singular reason for existence.

This is fine and all, and it's how most companies work, the issue arises when you think about the farmer being a consumer. The farmer is not reimbursed in full for their work, in other words, they become incapable of purchasing back their own labour in full. If the farmer the goes home and to the store, they cannot purchase the wheat they themselves created, it will cost more than what they were paid. This repeats itself in every company, the employees simply cannot be fully reimbursed for their work, not now and not ever. Yet, the workers also form the base of consumers, they are the vast majority of people who must be relied upon to consume these products. The end result is that everything seems expensive relative to salaries and you will, at some point, have to have a violent economic event to correct the markets as consumers simply run out of money.

Now that's not accurate in its entirety and it's a critique from the 19th century, but it goes to show that we have always recognised this being an issue. We just deal with it by accepting that some people will be unjustly hurt in regular recessions in the boom and bust cycle and move on – there's no just way of doing things without entirely removing companies from the picture. That's the way our economy is doomed to work, and we just have to accept it and move on unless we want to literally outlaw companies and organise production on a national level.
