FPAlpha: Again, the striking logo similarity and lack of mentions of real-world defense contractors strongly implies that Stark Industries is a fictionalization of Lockheed Martin or Northrop Grumman, and those companies, as I understand it, simply don't make civilian products such as vacuum cleaners or smart phones, in large part because they would likely have to have entirely separate divisions to ensure that they gained no unfair advantages from the government-contracted work. Consider this dialogue:
Obidiah: Tony, we're a weapons manufacturer.
Tony: Obie, I just don't want a body count to be our only legacy.
Obidiah: That's what we do. We're iron mongers. We make weapons.
Notice he
doesn't add "and electric cars, energy-efficient dishwashers, and world-class vibrators", and nor does Tony.
This whole thing is still full off unrealistic events but then we are talking about comicbook superheroes and you need to dispense with realism or 90% of them would not work.
No
duh. But I think, given the evidence, it's more realistic to assume the original arc reactor was built as part of a defense contract and that the filmmakers are unconcerned with the real-world implications of such a detail than to suppose it
wasn't.
