You have to realize that these big corporations use a lot of people from other countries. I work at a large tech company and the lobby congress for more 'immigrants' because they can get them to work for less money rather than hiring here. The larger the company the more this happens. Half the people I work with are from India and my company lobbies congress for more every year because we are a global company. I got laid off and luckily I got hired back. Every year when it is time for reviews I get reminded about 'how much I make'. This is multi, tens and tens of billion dollar a year tech company.
