Companies that build scale for the benefit of their customers and shareholders more often succeed over time.

I have gotten disturbed at some of the Democrats' anti-business behavior, the sentiment, the attacks on work ethic and successful people. I think it's very counter-productive.

The toughest are people mistakes, when you put the wrong person in a job. Sometimes you're too slow to move them out. Or not getting the right people involved to solve a problem, or doing something out of anger; you learn, just don't do that.
