No, but they have union agreements for minimum wages (enforced across sectors) and they have excellent welfare for those without a job (to the point that being a bastard boss and merely giving people scraps wont going to land you many workers).
Plus, as societies they have a basic decency, absent from other more exploitative societies.
Sweden, Norway, Denmark and Switzerland do not have minimum wages.
Yet none of them were overwhelmed by the abuse of homeless labor.
