Infinite Jobs to Be Done

Marc Andreesen was the cofounder of Netscape.

“If you believe human wants and needs are infinite,” said Andreeseen (sic), “then there are infinite industries to be created, infinite businesses to be started, and infinite jobs to be done, and the only limiting factor is human imagination. The world is flattening and rising at the same time. And I think the evidence is overwhelmingly clear: If you look over the sweep of history, every time we had more trade, more communications, we had a big upswing in economic activity and standard of living.” (p. 231)

The Sheer Openness of American Society

While these are the core secrets of America’s sauce, there are others that need to be preserved and nurtured. Sometimes you have to talk to outsiders to appreciate them, such as Indian-born Vivek Paul of Wipro. “I would add three to your list,” he said to me. “One is the sheer openness of American society.” We Americans often forget what an incredibly open, say-anything-do-anything-start-anything-go-bankrupt-and-start-anything-again society the United States is. There is no place like it in the world, and our openness is a huge asset and attraction to foreigners, many of whom come from countries where the sky is not the limit.
Another, said Paul, is the “quality of American intellectual property protection,” which further enhances and encourages people to come up with new ideas.
. . .
The United States also has among the most flexible labor laws in the world. The easier it is to fire someone in a dying industry, the easier it is to hire someone in a rising industry that no one knew would exist five years earlier.

Tenure and the Market as Protectors of Free Thought

Mark Blaug as a young tutor at Queens College in New York, endorsed a student petition protesting the firing of a left-wing tenured professor for having refused to co-operate with the Un-American Activities Committee. Less than a day later, Blaug received a note from the President of Queens College, telling Blaug that his choice was either to resign or be fired. He resigned.
Fortunately, he received a grant from the Social Science Research Council to complete his dissertation, after which, again seeking employment, he obtained a job interview at Yale:

(p. 77) In the course of the interview, I felt impelled to explain how I had lost my previous teaching position at Queens College. I always remember how Fellner cut me off, saying: ‘We don’t want to hear about that. This is a private college and what transpired at a public university a few years ago is of no concern to us.’ I never had a better demonstration of Milton Friedman’s thesis that a free market, by multiplying the number of probable employers, is more likely to secure liberty for the individual than a socialist system in which the state is a monopsonist.
