I think the reason is that, at some level, Wadhwa believes that immigrants make better entrepreneurs than (native-born) Americans. He's never said that outright, but that's been a theme in his writing for a while. For example, from the article: America has lost an entire generation of entrepreneurs and innovators and bolstered its global competition. That is also why the proportion of immigrant-founded start-ups in Silicon Valley fell from 52 percent in 2005 to 44 percent in 2012 and is probably even lower today. It's possible that a lower proportion of startups are immigrant-founded because there are fewer immigrant founders, but it's also possible that there may be more native-born Americans becoming entrepreneurs. One can't tell from just this statistic. If the ratio has changed because of an increase in American entrepreneurship, then Wadhwa's argument becomes that it's bad for the U.S. if more Americans become entrepreneurs. Which is weird. And being an American myself, something I find quite offensive.
