From today’s WaPo:

About 25 percent of the technology and engineering companies launched in the past decade had at least one foreign-born founder, according to a study released yesterday that throws new information into the debate over foreign workers who arrive in the United States on specialty visas.

Scott McNealy, chairman and co-founder of Sun Microsystems, “is among the advocates for an expanded visa program, writing editorials, calling members of Congress and supporting political action committees.”

He asks a pretty good question, I think: “Why would you have any arbitrary number on smart people?”
