I've actually been thinking about this quite a bit lately, and I've come to the conclusion that this is really how America ends. Wallowing in its own stupidity, locked down by the authorities because we're afraid of everything we don't understand (which is everything, due to ignorance), and decrying any interest in something other than pop culture as suspicious.
When I was a kid some forty years ago, it was still possible to learn, make, see, and do things without nine layers of security clearances and being met with "you can't do X because terrorists/drugs" at every turn. Now, the only reasonable explanation for why you're interested in something is because you do it for work. And because some company makes you do it for money, now it's suddenly okay. Building anything with wires sticking out that beeps? Terrorist.
Learning chemistry at home? Terrorist or maybe the next Walter White. Interest in trucks/trains/planes and not a truck driver/engineer/pilot? Terrorist. Interested in power generation/distribution but not a power EE? Terrorist. Interested in computer security research? Cyberterrorist! Aiieeee! I could go on and on and on here...
Hey wait a minute - you know how most of the good people in those fields got there? Because it's what interested them before they did it as a job. In the past, there were always ways to learn about these things, particularly as a kid. Folks willing to show you around, show you what they did, explain how things worked, and sometimes let you help. I can't tell you the number of things I got to try out as a kid that would now get somebody fired and probably grilled by some three letter agency. But it's because of those experiences that I'm a successful electrical engineer today who loves it as both his profession and passion. I didn't just pick a job off the list, say "that looks good and pays well", and then decide to spend my life doing it. The folks I know who did that have already washed out and gone looking for something they enjoy more.
The next generation is boned. Their curiosity about things is being actively destroyed when its met with suspicion and investigation rather than encouragement or better - "Ssh, don't tell anybody, but put this hard hat on and come with me..." This is just one example.
Yeah, there's definitely a racist problem here as well (it *IS* Texas, folks...), but I think focusing on that is missing the real point. It's not just non-white kids. The powers that be have taught us to regard everything with suspicion rather than curiosity. Yet I ask you - how many kids have you seen today who are terrorists vs. how many have you seen who need to learn about the world and figure out what they want to do with their lives?
