...You are using "wealth" in a way completely foreign to how I have ever seen it used linguistically. The abundance of resources available to an individual that we call "wealth" colloquially being transferable or tradable is basically the hallmark of a market economy. It can absolutely concentrate within one, because if it can be traded, it can absolutely be not traded decreasing the velocity of that value transfer to zero. So... Yes. If only one or a handful of people are buying, because everyone else is having to sell to stay alive, then wealth does, in fact, concentrate.

Again, wealth is created, not "concentrated". The term "wealth" means the dollars you would get if you sold everything.

> wealth does, in fact, concentrate

Nope, because the people trading with you thought the exchange was of equal value, or they wouldn't have engaged in it.

		The term you're looking for is "surplus". The consumer sees a surplus of value because the price they paid is below the maximum they're willing to pay, and the producer sees a surplus because the price they charged was more than the cost to produce the good. In this economic system both parties benefit. Economic surplus is the thing that is "created" with every transaction. "Surplus accumulation" as a concept doesn't make any sense, and is isomorphic to what you think people are saying when they use the phrase "wealth accumulation." You should update your definition of "wealth".
