Damn I came in here to say the same thing and feel sad at myself now too.
So not to be racial but from an American standpoint I liken it to hiring an American who happens to be Chinese versus an engineer from China.
For the first, they are American, their family is here, their life is here - where would they flee to?
For the latter, they're here temporarily most likely. So why not take the risk and get a big reward?
Well the issue is because of this stereotype, companies may not differentiate between the two, or may even pass up an amazing engineer from China because of their racial (well nationality) bias.
I remember reading about a couple incidences of American engineers(?) being falsely accused of stealing secrets which led to them being fired and shamed.
Those are just people, let's not lower our standards
