Fast food places hire Mexicans and get rid of whites and hire more Mexicans.

All the fast food places used to hire whites.  Then, they get rid of the white managers and replace them with Mexicans.  The Mexicans cut the hours of the whites and hire more Mexicans.  When all the whites are gone, they replace them with more Mexicans.

So, you get hired by another fast food place with a white manager.  But the same thing happens there.  They replace him with a Mexican.  He cuts your hours and hires another Mexican.  Once you're gone, he hires another Mexican.

So, you try to go to another fast food place.  But all the white managers have been replaced by Mexicans, and they only hire Mexicans.  So, you're left homeless sleeping under a bridge.
