Labour for me is human productive effort towards achieving set target.To answer the question, labour may be wealth, in the sense that when others labour while you fold your harms and watch from where will the wealth come from? Wealth creation cannot be separated from human effort both mental and physical.
Of course labor is considered an asset, labor is not only an asset but a valuable asset. The more industrious a nation is, the more developed it is. A lazy nation can never prosper on earth. Industrial revolution and agricultural development in a country requires an industrious nation. Japan, China and the United States of America are known as the most advanced and prosperous nations in the world because of their hard working people.
