I disagree. And a black man/family is just as capable of achieving all those things, it’s just more difficult. I’d like to see the Waynes killed in a different way. Maybe by police in a race riot or protest? Still a successful couple with influence. Just a little more grounded, self-made, and living in a neighborhood with a culture, rather than a mansion on the outskirts of Gotham. Alfred is a family friend or brother who is left in charge of Bruce. Heck, maybe make him an aunt/female in this iteration. Batman could be more focused on his neighborhood, fighting police corruption and local gangs. He starts recruiting teenage Robins as a way to keep the gangs from getting to them.
As an aside, Batman is still Batman without his wealth and I wish that was explored in more stories. Batman is made by his will, drive, and obsession more than his money. Modern stories have just taken that aspect too far, with robot bat-suits, fleets of Batmobiles, and bat-rocket ships.
