Right.
The thing of it is that Iron Man's rogues gallery is so full of generic corporate/armored foes and superpowered thugs of varying ethnic and cultural origins that they're ripe with potential for characterization.
If anything, they're a movie producer's dream, as it's all cool looking guys with no substance in them... leaving them free to depict the character in whatever makes the most filmic sense.
I mean Crimson Dynamo need only be Russian, Living Laser can be whatever the want him to be (and not actually call him living laser), Radioactive Man can be emblematic of the pitfalls of breakneck industrialization in China, etc. etc.
