Summary
This quote suggests that there is always a significant demand for content that caters to a less discerning or intellectually curious audience. Those who choose to write articles, books, or create any form of media targeted towards fools, or individuals who lack critical thinking skills, are likely to attract a wide readership due to the sheer number of people who fall into this category. It implies that appealing to a larger audience sometimes requires compromising quality or catering to the lowest common denominator of intellect.
