> But all too often the resources to pay a living wage exist but the market has been manipulated such that the labourer won't be able to claim that.

These are orthogonal. A fair market price simply isn't equal to the price that is required to sustain someone's living. A fair market price also is not equal to the price that could be paid (i.e. the "resources available").

The laborer whose price is raised to some arbitrary limit that is above the market rate will find demand for their labor disappear in equal measure.
