I'd like to start a business and employ TG people who are transitioning or preparing to transition. A lot of us have trouble finding work, especially before or during transition. I live in a big city that's very accepting of TG people. I'd really like to offer jobs to TG people who want to come here from places that aren't so trans-friendly, young people who have been rejected by their families after coming out, people who have lost jobs after coming out, etc.
When I read about people who are really struggling to get by during transition, I fantasize about being able to say, "Hey, come to San Francisco and work in my pizza shop! Sure, it's not glamorous, and I can't afford to pay you more than $10/hour, but it's something to do while you transition and get on your feet in a trans-friendly city. And you'll get to work with other people who are going through the same kind of thing."
Realistically, I don't know what kind of business I would want to open, but it's something I'm seriously considering.
