What are the motifs in Buffett: The Making of an American Capitalist by Roger Lowenstein?

Shareholders' money is a recurring idea. One of Buffett's greatest complaints about American corporations is that the CEOs and upper-level managers have little or no relationship with the vast majority of their investors. In this climate, Buffett asserts, there is no commitment to use profits to benefit the shareholders first and themselves second. Thus, corporate bonuses and random unwise investments become the rule, often resulting in only small returns on investment for the stockholder and huge wealth for the executives.
