Personal experience but this is true as fuck. Westerners aka whites are the only ones outside the Japanese who are willing to work alongside others without issues. Anyone else? They'll behave for a few days or weeks and then fuck you over. They'll try to climb the ladder to only push you off and wave on their own kind. Had this happen to a relative. Best one for a job, black dude running things said nope. Few days later we get wind he hired his brother an absolute idiot. Now the business is tanking fast as more and more workers get replaced
