Fallacies of market economics and its conflict with justice

Well crap!

I ran out of reading material in the bathroom. With no more science fiction to read, I'm reading a new kind of fiction.

Market economics.

Here's what I've learned so far.

There's no justice in the market.

It was like an electric shock when this idea popped into my head. Here's the example which should be explored by others.

Somewhere there's a city square and people trade for foods and other items. Let's concentrate on food.

A man has apples for sale which means he has surplus apples and would like to eat other kinds of fruit or food.

Another man wants apples and offers to trade peaches for apples.

A fair bargain is reached where both get equal value. A peach is worth an apple.

Wow. Big deal. Where and when does anyone make money in a fair market? Answer: No one makes money in a free and fair market.

There can only be profit in the 'market' when one side finds advantage in the trade.

No justice in deceiving others. Is there?
