Charles Koch’s new book, Good Profit, is written for two different kinds of readers. The first is the entrepreneur who wants to build up a firm, as Koch did in spectacular fashion. So much so that an investment of $1,000 in the company back in 1960 would be worth $5 million today (if dividends had been reinvested in the firm). I’m not that kind of reader, alas. I’m the second kind, who wants to know how a company that foreswears crony capitalism can thrive, as Koch Industries did.
