Interestingly, minimum wage seems to be more likely in places with weak unions. In places with strong unions, there is often a de facto, negotiated minimum at least on a sector by sector basis instead. E.g. Norway has a roughly 50% unionisation rate, and no minimum wage in most situations, but most sectors are covered by negotiated agreements between the unions and employer organisations.
