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.
After doing the work, of course, you will get paid according to the work we do and if we continue to complete a job well then we will be able to get an income that we can save for something we want and it is very unlikely that someone will be able to achieve what they want without having an income that can meet their desires therefore we must be able to have a skill that we can do Do it in order to be able to provide income to be able to achieve what we want and rightly as you said, whatever we do must be able to provide income and do not let us do something that does not provide income, of course this will be very disappointing after being tired of working not being able to get income from the job.
