That is not enough. We want to be alive as human beings, not as caged animals. It follows that everyone, who wishes to stay alive as a human being, should understand at least the basics of economic lore. Those who have no such interest should wisely stop reading at this juncture. Were I to teach economics, I would try to make these points clear.
Man is a profit-seeking creature.
However, I will embellish it enough to remove a common misunderstanding. The word profit is so affiliated with bookkeeping procedures that I can anticipate an assumption here. Some will be certain I have said that everyone wants to profit in terms of dollars. This is decidedly not so. Many are not interested in dollars, as such.
