Opening a comic shop is not easy. There is a lot of responsibility to deal with. Not everyone wants to do it. That might not be Skyvolt's thing, no matter his financial situation. Besides, that doesn't really help diversity in comics.
As for writing comics, I can only speak for myself here. I wrote my own comics in 6th grade. It was a hobby. Now, I'm at an age where I have a lot of hobbies and writing my own comics is not something I want to do unless I'm getting paid for it.
One thing I do encourage younger people that I know to write. And not just comics. And of course to stay in school and go to college. This way more minorities can be in the position to write comics, if that's what they want to do.
It's great that you are taking the time and effort to make your own comics and video games. But not everyone wants to do that.
And lastly, there is nothing wrong with wanting and asking for something better than what we're seeing now.
