I brought up the social system because you can see that everyone in this thread arguing against you is saying that your “excellent welfare system” is the reason why your income is lower than the corresponding American programmer’s. The massive taxation is obviously a big factor to your reduced income, but let’s look away from that for a bit and just focus on the American companies.
American companies in America pay more because the costs of doing business in America are much lower and there is a greater availability of loans and funding.
American companies in Europe pay more because they have the advantages listed above that local European companies don’t have and they have the resources to invest in a global expansion.
That’s it. That’s the answer.
Is this like when they made the kilogram some function of the speed of light instead of the weight of a metal ball in a French museum?
