What sort of person seeks to humiliate an entire group of people simply on grounds of race or nationality? Well, at present, the sort of person who supports the wall between Mexico and the USA. Yes, it may give some groups of rent-seekers a feeling of enhanced security in the ability to accrue their ill-gotten gains. But above all, it gives the American yahoo class the feeling that they—the self-supposed better people—have shut out Mexicans in the most brutal possible fashion, by physically fencing them out as if they were dangerous wild animals.
