Is it also affirming a stereotype that Indians are incredibly rich? Because that's how Raj is portrayed and the show mocks his wealth on more than one occasion.
Similar to a comment above , is it affirming that all Indians in the show are rich or that the character is of Indian background and is rich.
Having watch the show, the show never mocks his wealth but his dependence on his parents wealth (and even has an arc where he strives to be independent for it).
