White people believe that the system has failed them. The "American System" should naturally lift them up into those high salary positions and all they have to do is exist within this system.
Look at Hank Hill for example, he works for a small propane business, never asks for a raise, hasn't competed for any type of high level position because he believes the system should take it's natural course and "lift" him up. Meanwhile, his foreign neighbor developed his tech skills, competed for jobs, moved around the country, and makes a lot more money than Hank. Hank doesn't even know how to work a computer, but someone like Hank will say, "the system has failed me, look at these foreigners taking American jobs!"
This is why they're so mad, they are swinging at anything that moves. DEI, holidays, etc. etc. Instead of putting that mirror in front of themselves.
