Try to ponder my statement for a while to figure out why it's a truism. You probably won't succeed but it won't hurt to try.The vast majority of times I have seen that is not the case. They pick immigrants because they represent a better value to the company.
Its always funny when you do this, and I think you do not even realize what you are doing.
The implication of your statement is that only racists use cherry picked examples from dummies who have little perspective. Not only racists will do that. Sometimes people will use a study to back up the evils of say American invasion into Iraq. That person might use a number that has over and over been shown to be too high. They likely use that number because it fits their narrative even when presented with evidence that shows they are wrong. You can test to see if they are doing this, because that same type of person will never address the data, and only attack the person who presented the data.
See what I mean?
This is one of those things you'll never figure out any more than the racists here will ever figure out the reason for their diminished station in life.
