There are so many incorrect and factually wrong statements here, I laughed, out loud, for a while.
You actually said that prices are determined by sellers, which is dumbfoundingly wrong.... I'm going to throw you a bone on only this one, demand drives pricing, always will, because no going concern can limitlessly sell goods at a loss, they exit the market. No going concern will sell a product NO ONE buys, and no going concern will sell at a price no one will pay, they will lower it until it sells. Supply ALWAYS chases demand, as does pricing.
The effort and time to correct all of the rest would be exorbitant; a solid community college economics course would be a good place to learn actual economic function, as what you're posting is vastly incorrect.
Really, you shouldn't attempt to discuss economic theory, you're not conversant at all.
