It's true very few actually suffer from gender dysphoria. But as a counterpoint, you can hardly go anywhere in any city without seeing several obviously trans individuals. Probably not higher than 2% of all the people you see, but definitely more than 2% of just LGBTQ people. It has obviously exploded in popularity, and IMHO not just because they feel more able to outwardly express it. To explain why it's so rare in business owners, well, it's not surprising few would own a business. Trans people have to scrape by with whatever job they can hold while paying for the surgeries and hormones. It's why they pushed so hard to be accepted in the military; free healthcare is a requirement to be openly trans, and holding down a desk job in the military is a lot easier than starting a small business if you're undergoing multiple surgeries and constant mental stress and mood changes.
