I think you forgot to take into account the fact that that Europeans don't work as much as North Americans: https://data.oecd.org/emp/hours-worked.htm https://data.oecd.org/emp/hours-worked.htm That doesn't entirely explain why revenues in the US are that much higher than revenues in Europe however. The fact that the current trade value of the € against the $ is significantly lower to what it was ten years ago (European debt crisis) also partially explain the different revenues between the two continents.
