By the same token, if you asked me: "Williams, how many minutes today have you been thinking about white people?" I'd probably say, "You'd have to break the time interval down into smaller units, like nanoseconds, for me to give an accurate answer." Because people don't care about you one way or another doesn't mean they wish you good will, ill will or no will.
If Professor Alchian's vision of how the world works is correct, what are its implications? A major implication is that one's destiny, for the most part, is in his hands. In other words, how you make it in this world, for the most part, depends more on what you do as opposed to whether people like or dislike you. In order to produce a successful life, one must find ways to please his fellow man. That is, find out what goods and services his fellow man values, and is willing to pay for, and then acquire the necessary skills and education to provide it. Whether your fellow man cares about you or not is largely irrelevant.
