Sajay Samuel: How college loans exploit students for profit

1,126,427 views


"Once upon a time in America," says professor Sajay Samuel, "going to college did not mean graduating with debt." Today, higher education has become a consumer product -- costs have skyrocketed, saddling students with a combined debt of over $1 trillion, while universities and loan companies make massive profits. Samuel proposes a radical solution: link tuition costs to a degree's expected earnings, so that students can make informed decisions about their future, restore their love of learning and contribute to the world in a meaningful way.

Sebastian Junger has seen war up close, and he knows the impact that battlefield trauma has on soldiers. But he suggests there's another major cause of pain for veterans when they come home: the experience of leaving the tribal closeness of the military and returning to an alienating and bitterly divided modern society. "Sometimes, we ask ourselves if we can save the vets," Junger says. "I think the real question is if we can save ourselves."

What if we could peek inside our brains and see our dreams -- or even shape them? Studying memory-specific brain cells, neuroscientist (and ex-hacker) Moran Cerf found that our sleeping brains retain some of the content we encounter when we're awake and that our dreams can influence our waking actions. Where could this lead us? "Neuroscientists are now giving us a new tool to control our dreams," Cerf says, "a new canvas that flickers to life when we fall asleep."
