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.

The iPhone is made on a global scale, and it blends computers, the Internet, communications, and artificial intelligence in one blockbuster, game-changing innovation. It reflects so many of the things that our contemporary world is good at - indeed, great at.

I pay people very, very well - probably more than I have to. But that costs me less money in the long run because I'm not having to constantly train somebody. I pay them enough that they don't go seeking a higher scale at the next restaurant.

ER' was an all-consuming universe, but I don't have a single regret. It gave me some of the greatest friendships I have and afforded me one of the rarest commodities in an actor's life, which is the financial security to pick and choose jobs for factors besides the paycheck.

I've read hundreds of cookbooks. For my money, they are the bird.

It's hard to have any idea of how much money is enough to finance an appropriate lifestyle in retirement. But if a lump sum is translated into a monthly income, it's much easier to determine whether you have enough put away to afford to stop working.
