So many in our society today regard profit as evil. The contrary is true. Profit is one of the highest of virtues in our capitalistic system because it involves the free exchange of value. The person buying a product views said product at a higher value than he is willing to give up for it, and voluntarily, without coercion, expresses that value through the exchange of currency to the seller. Profit shows that the producer created more value than it cost to produce the product.
This video by the Atlas Network also shows which types of profits are gained at the expense of others, i.e. those that profit via government special interests and subsidies.
