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.
Labour is wealth because in so doing, you're going to be paid from it and this will help you to gather up to a reasonable amount of money for achieving something in life, we don't have to undermine the labour market, because our physical, mental and natural way of thing is being channeled towards the dignity in labour from what we do to earn from, labour come come in any form, as long as you will be paid for doing something constructive and in others people demands.
