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.
In my understanding, if we have no effort or labor to do, we will not accumulate wealth in the future, because most of the time people exert effort, especially if you are an employee, they are only focused on their thoughts that they need to do their job well in the company so that they can get paid or receive money.
Why? Its either they have a family that needs to be helped or supported in short responsibility that must be fulfilled, especially if their salary is only enough or even insufficient, it will be difficult for them to save so that they can have wealth for the future.
