Automation is coming. We can't stop it. Together with Globalization and various "free" trade agreements, the US worker is ..effed. We are going to have the well-paying STEM jobs, the lawyers, bankers, doctors, therapists, the super low wage unskilled laborers in a race to the bottom, trying to compete with machines, and a huge, empty nothing in the middle between those groups.
And that's going to happen sadly before we reach Star Trek utopia, and there will be large-scale civil unrest, even in the US, within the next 30 years, I'm betting on it.
And let's not even talk about impoverished countries with exploding populations that are already struggling to provide jobs - an endless cycle of regional warfare, an endless Arab Spring.
