So here is a scenario.
In location A you have the raw materials, a tanner who makes and sells leather.
In location B you have the skill set, a cobbler who turns leather into shoes.
In location C you h ave the market, people who want to buy shoes.
The tanner would love to sell his leather to the cobbler, but the cobbler doesn't have enough money to make the initial investment. He has skills but no resources. He asked the tanner for credit, explaining that if the shoes do sell at location C he'll have enough to pay back the tanner. The tanner refuses saying that it is too risky and asks who will cover the transportation costs. There is a driver that goes between towns A, B, and C, but he only drives when hired and doesn't invest in goods in any location.
Along comes an entrepreneur. He sees this mess and say "I will use my personal money to cover these transactions. I will purchase the leather at point A, hire the driver to transport the leather to point B, hire the cobbler to work the leather into shoes, hire the driver to transport the shoes to point C, and sell the shoes at point C. If I guess correctly there is a market at point C and I will recoup my investment and also make a profit. If I guess incorrectly, I am the only one who loses money; the tanner, the driver, and the cobbler all get paid."
Who is being exploited and who is doing the exploiting?
