No, stop pretending that labor supply is adjustable outside some narrow range. Wage earners at the bottom don't withdraw from the labor force in order to help those left in it earn a higher wage. They work for less, until a floor is reached. Then they work another job, driving wages down further, unless there are none, in which case they eat less. And when there are fewer jobs still, they subsist in other ways (charity, crime), or fail to subsist. Almost no one is moral enough to starve.
