De acordo com o banco de dados de quadrinhos da DC , sim, Bruce Wayne é o homem mais rico de Gotham City:
Kaiyo has stripped both Batman and Superman of any memories of their former lives. Having since learned that he is the richest man in Gotham City, Bruce Wayne is intent on taking advantage of it. Naturally, Alfred is concerned.
" Gotham Cable News ", um site falso criado para promover o filme The Dark Knight , confirma que isso também é verdade no universo da trilogia de Nolan:
Where does the richest man in Gotham move when his house burns down? For Bruce Wayne, the answer was easy - find the priciest luxury tower in town and buy the entire top two floors.
O script para Batman: Year One concorda:
The 25-year-old heir to the Wayne millions declined to comment on his return home after 12 years abroad. We'll keep you posted on Gotham's richest and best looking native son.
O site DCAU Resource vai ainda mais longe, e afirma que Wayne não é apenas o mais rico homem em Gotham City, mas também o homem mais rico vivo:
Gotham is famous for being home to the richest man alive, Bruce Wayne, and the city's resident protector, Batman who both technically live outside of the city.
A Enciclopédia Essencial de Batman diz que Bruce Wayne é o homem mais rico do mundo , com ativos líquidos de aproximadamente US $ 7 bilhões nos EUA
Esta figura é baseada na lista da revista Forbes dos personagens fictícios mais ricos do mundo, que aparentemente usaram a trilogia Nolan exclusivamente para seus dados. No entanto, este site coloca o número é muito maior, bem acima dos US $ 25 bilhões dos EUA; essa disparidade é surpreendente, já que a segunda fonte usou o mesmo material, mas chegou a um número drasticamente diferente.
Eu não incluiria isso se não tivesse as citações mais canônicas acima, mas um usuário em Comic Vine é um caso bastante strong para Bruce Wayne ser o homem mais rico de Gotham, e um dos mais ricos homens no mundo:
Bruce Wayne is technically a Trillionaire with billions in liquid Assets.
He literally owns something like 1/3 of Gotham's land, some of the most valuable land in the country, before NML and after he owned all that land plus made tons of cash by investing in all the businesses he financed. That's without considering the Wayne Manor and every thing in it. Wayne Foundation, Wayne Enterprises, and all the various other subsidaries and shell companies he owns.
The only people that can match him is Tim Drake due to technically owning all that stuff as well plus his own millions he had before and the investments he's made, but that depends on your outlook of that. The other person is Ra's Al Ghul who can only compare due to being alive for so long.
Imagine if someone owned 1/3 of all the land in New York, 50%+ of all the businesses, and something around 1/2 the buildings. That person would be worth in the Trillions and that is what Bruce owns, not counting anything else
