Looking at the spreadsheet I noticed, that all the jobs in the US easily make twice the money then the european ones. Since according to Google 1$ is about 0.9€, if you make 100k in the US this should roughly translate to 80-90k €.
Now I do get that in the US you have to take care of all kinds of insurances yourself, but it can't possibly be as much as double the salary or am I wrong?
So if someone could roughly sketch why the huge salary difference that would be great.
