What double? A corporation is a corporation is a corporation. Is there a difference? If yes, then between what?If you'd said that people come to the US to work for free for MS or big pharma to help them deliver product for free like you say they should, I would respect the logic.

"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
