<p>The sad truth is, hard sciences and engineering are not that attractive to many American kids. Schools need to fill their departments. It has nothing to do with diversity. There are plenty of Asian American kids for that purpose. I am sure colleges always work hard to attract more African American and Hispanic kids. They need the foreign kids and, in many cases, their paying ability. Without them, many many departments would be scaled back or shut down.</p>
