Yeah, I shouldn't have even linked that article. It was the first I came across and that author is a real ass. Some of the comments gave it back to her. People don't pay thousands a semester just to read a textbook.
"In some countries, such as Britain and America, poor pay and job prospects are reflected in the number of foreign-born PhD students. Dr Freeman estimates that in 1966 only 23% of science and engineering PhDs in America were awarded to students born outside the country. By 2006 that proportion had increased to 48%. Foreign students tend to tolerate poorer working conditions, and the supply of cheap, brilliant, foreign labour also keeps wages down."

They were from India, Asia, the Middle East, North Africa, and yet they were Harvard students, Stanford students, Rice students. It just reminded me that American higher education is not American. It’s for the whole world.”
Then 22 and only a semester shy of graduation, he contacted the American colleges that had accepted him to graduate school. He asked if they would take him instead as a transfer student — immediately. Rensselaer Polytechnic Institute said yes, and within weeks, he was en route to Troy, N.Y., from Tehran.
“I was in a state of shock,” Dr. Farvardin, 54, recalled. “I had very little money and no knowledge of the English language.”

(and that was 20 years ago)
