I see three forces militating in favor of growing inequality: increasing measurement of worker value added, automation through smart software, and globalization.

Look at electricity in human history - it took a few decades for electricity to really revolutionize the American economy. And the Internet will be the same. At some point in the future, we will arrive at a new era of low-hanging fruit.

When you look at the actual data on technological innovation, one thing you see is that what I call the 'low-hanging fruit' has been exhausted. So radio, flush toilets, electricity, and automobiles - a lot of very basic inventions - have spread to almost all households.

I double majored in English education and theater with a musical theater minor. Teaching is the only thing that makes me as happy as performing.

I'm always just happy to see when models are working hard, doing well, and really, above all else, doing good things. I love when they work for charities or inspire education. Look at Karlie Kloss promoting education - that's wonderful.

Progress for black Americans depends on good schools because education is the last great equalizer.
