Answer 1

The introduction of interchangeable parts, the cotton gin, and labor unions led directly to the mass production of goods. This resulted in a decrease in the cost of production, allowing goods to be made and sold at more affordable prices. The patent system also played a role in this process by incentivizing innovation and protecting the rights of inventors. As a result, consumers had access to a wider variety of products at more affordable and competitive prices.
