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 you can have money if they pay when you do labour or work for someone, so it is wealth, as long as you have a healthy body and can do anything to gain profit then that is a big wealth, because there is a lot of opportunities to earn, some people is born from wealthy family and they have big advantage but as long as we are free from sickness we are also lucky.
