I have thing or skill. You want things or skill. Depending how many people want thing or skill, I get paid fairly for it

This is famously not how capitalism works. What you're describing is primitive manufacture as it happened in medieval workshops: a class of tradespeople who owned their tools and their workshop and sold the fruits of their own labour by themselves.

Capitalism works differently because the people with the skills don't own the tools or the workshop, the workshops and tools are owned by people who happen to have generational wealth, called the capitalist class. These people don't have skills, they have money, and with this money they acquire means of producing things, like factories. Then, the skilled workers who don't have the money to buy such factories, enter into "free and voluntary" contracts (not so free or voluntary when unemployment exists) in which they get paid not according to how much they produce, but according to how much they can manage to scrape from the capitalist owner, which always gets a profit from the labour of said people.

This has been well-understood for 200 years since the first formal definitions of capitalism appeared, what you're describing is 13th century primitive capitalism
