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

Well-trained and dedicated employees are the only sustainable source of competitive strength.

I am not an economic determinist. If I were, I would throw up my hands; I just would not bother. I think it's wrong to be an economic determinist. I think it's wrong to simply say, "Well, inevitably, if you're poor, you're going to get a lousy education; if you're lower-middle class, the cards are going to be stacked against you, and you'll probably never get anywhere".

When top executives get huge pay hikes at the same time as middle-level and hourly workers lose their jobs and retirement savings, or have to accept negligible pay raises and cuts in health and pension benefits, company morale plummets. I hear it all the time from employees: This company, they say, is being run only for the benefit of the people at the top. So why should we put in extra effort, commit extra hours, take on extra responsibilities? We'll do the minimum, even cut corners. This is often the death knell of a company.

If you give up on democracy, you might as well give up on everything.
