The cost of living is higher in France, and much higher in England, which makes up for much of the difference. Norway gets like 19 euros an hour, but their cost of living is way way higher. It is very expensive their. Don't just look at money per hour, look at the cost of basic commodities, food, gas, etc. Plus how much of those wages are taxed. More taxes in Europe. Common sense. Also, France gets five weeks of paid vacation, not eight.
that pounds sterling are more valuable than dollars so the "economic truth" that a higher minimum wage causes inflation is a lie.
