"Anyway, no drug, not even alcohol, causes the fundamental ills of society. If we're looking for the source of our troubles, we shouldn't test people for drugs, we should test them for stupidity, ignorance, greed and love of power"

The text in this quote suggests that drugs, including alcohol, are not the source of society's issues. Rather, the author suggests that the issues originate from qualities such as stupidity, ignorance, greed, and the desire for power, which can not be tested for through drug screening. Basically, the author is arguing that we need to focus more on the underlying elements that cause societal problems and address them straight, instead of just evaluating and punishing individuals for drug use.
