theodp (442580) writes "The weeklong Hour of Code kicks off tomorrow, with Mark Zuckerberg and Bill Gates doing their part to address a declared nationwide CS crisis by ostensibly teaching the nation's schoolchildren how to code by snapping together Google Blockly puzzle pieces. An apparent act of noblesse oblige, but a recent NY Times Op-Ed by economist Paul Collier criticizing Zuckerberg’s FWD.us PAC as self-serving advocacy (echoing earlier criticism) serves as a reminder that Zuckerberg and Gates' Code.org and Hour of Code involvement is the Yin to their H-1B visa lobbying Yang. The two efforts have been inextricably linked together for Congress, if not for the public. And while Zuckerberg argues it's "the right thing to do", Collier reminds us that there are also downsides to the tech giants' plans to shift more bright, young, enterprising people — who he calls "fairy godmothers" — from the poorest countries to the richest. "An open door for the talented would help Facebook's bottom line," Collier concludes, "but not the bottom billion.""
