We never used to blink at taking a leadership role in the world. And we understood leadership often required something other than drones and bombs. We accepted global leadership not just for humanitarian reasons, but also because it was in our own best interest. We knew we couldn't isolate ourselves from trouble. There was no place to hide.

We don't have to sit by and watch our meritocracy be replaced by a permanent aristocracy, and our democracy be undermined by dynastic wealth.

Liberals are concerned about the concentration of wealth because it almost inevitably leads to a concentration of power that undermines democracy.

There is a crisis of public morality. Instead of policing bedrooms, we ought to be doing a better job policing boardrooms.

In my first remarks as Chairman of the Federal Communications Commission to the agency's terrific staff, I stressed that one of my top priorities would be to close the digital divide - the gap between those who use cutting-edge communications services and those who do not.

It's interesting now; with social media, you are actually interacting with fans.

The Internet has introduced an enormously accessible and egalitarian platform for creating, sharing and obtaining information on a global scale. As a result, we have new ways to allow people to exercise their human and civil rights.

Social media websites are no longer performing an envisaged function of creating a positive communication link among friends, family and professionals. It is a veritable battleground, where insults fly from the human quiver, damaging lives, destroying self-esteem and a person's sense of self-worth.
