People used to sometimes start businesses in order to bring a high demand product to market at a much more affordable price. Often, because that person actually gave a shit about the things they made/sold.
Sometimes these people would even go on to make more money then if they had just went along with the market rather than undercut it.
But all of that requires long term thinking. And some actual character and principle in the people who do it. Which is apparently all just way too much to ask in 2026.
