You are missing the point. Bill isn't looking for coders, cheap or otherwise, here - he has plenty of them across the planet. He is looking for "exceptional talent" to be based in the US (hence the visa issue), and that doesn't come cheap, wherever it may come from. As a matter of fact, he has in the same breath asked Capitol Hill to beef up America's education infrastructure so that more such "talent" is produced natively. If you read his statement carefully, the issue for him is flexibility in planning, not cost. Cost is never the only driver of business decisions, contrary to the popular misconception among large sections of the Left.

Isn't increased flexibility in planning wanted because it is somehow, actually a reduction of some costs. Here, a "more flexible" workforce got paid less.
