Let's bring a new wave of land grant universities. The feds own like ~90% of Nevada, let's put a top tier research university smack dab in the middle of it. Put up some new facilities, draw faculty away from other top tier universities/the rest of the world, and start pumping all these bright, but otherwise undistinguished kids into a place where they CAN distinguish themselves. All that sweet, sweet federal cash flows in, and you can bet people will set up shop around it. For the feds, it's a cheap investment, but one that has paid for itself a thousand times over.
Make it a public bell labs in the desert, then do it across rural America. Huntsville (kind of) did it, why can't we do it again?
