I think that before the Comics Code of Authority came out and emphasized on the ridiculing jokes on racial minorities, I suspect it wasn’t really something that comic staffs really thought about in general unless it was personally pointed out to them, not necessarily out of malice, but more so out of blissful ignorance in just grabbing inspiration for jokes anywhere they thought they could get away with it. I want to emphasize is that people, whatever background they come from, shouldn’t judge someone they’ve never met based on what they see in comics, movies, TV, etc. because I feel that human beings have an obligation to do proper research when it comes to learning about groups of other human beings. That said, that doesn’t mean immigrant/race-related jokes shouldn’t be put into question. Even Jack Kirby did bad by drawing Whitewash Jones based on the unfortunately popular Sambo and minstrel blackface stereotypes, despite him later helping create the more respectable a Black Panther. With how racism can affect art today, I suppose a possible course of action to take is that only white people can be drawn with exaggerated caricatures, but I’m also not sure how that would hold up.
