“Suppose there was a large, U.S. government-operated program that permitted U.S. employers to hire nothing but White Anglo Saxon Protestant (WASP) college-graduate men between the ages of 22 and 30.
Suppose that program, more narrowly, allowed major U.S. employers to discriminate in favor of descendants of men who had graduated from an Ivy League College before World War II. (After WWII the Ivy League dropped its restrictive admissions practices.)

If that were the situation, there would (understandably) be hell to pay. Lawsuits by the dozens, marches, demonstration, strikes, civil unrest, discussions on the evening news, and maybe even more appropriations for the just-about-starved U. S. Equal Employment Opportunity Commission.
The sad truth is, if you change a few words, that is exactly what the H-1B program permits; but instead of WASP males, the favored population is male Indian college graduates, perhaps largely from the south and west of India”
