And since there’s no substantial difference between a businessman and an investor (i.e., both constitute an entrepreneur), a businessman’s emphasis on prioritizing customer (e.g., see Jeff Bezos) and an investor’s emphasis on market price quotations (e.g., see Warren Buffett) both make all the more sense.

An exception: if the consumer cannot find what he wants, and if he doesn’t give up, then he becomes the producer for himself.
