A new proposal from Donald Trump could increase economic growth while securing the borders. Trump laid out his idea at a campaign rally today: “We all know that these enviros with their pollution rules are killing our economy. I mean any idiot can see that. What’s the fastest growing country right now? China. I know, isn’t it crazy that Obama just lets that happen? Well, look at their cities. You can’t walk outside unless you have a gas mask—one of those World War I things, you know. It messes up your hair, though. We need more pollution like that, so we can grow, and all the immigrants, the people who want to come here and take our stuff and rape our women and blow us up, they’ll see that and they’ll say, ‘No way I’m going there.’ So we’ll be growing the economy and we’ll be safe, as long as we wear our gas masks.”
