Capitalism is fundamentally simple. You own the means in production. The stove you bought to use in baking those pies you sell on Facebook Marketplace, you own it and dictate what to do with it. You also get 100% of the profit if any. What you decide to do with your capital---something that is made solely to produce other stuff---or profits, have nothing to do with capitalism. Capitalism allows for you to be in the position to decide what you want to do with them. I can decide to use my printer to scan old used books and archive them on my computer for public use. I can put some of the books up for sale in digital format and use the profits to buy a better printer, or upgrade the archive with better software. Whether you decide to do good or bad, is up to you. You are in complete control.
