Earlier quoted context omitted.
Avg dev salary in Dallas: $93k. Avg dev salary in Berlin: $55k. There's a saying you should be careful with what you wish for, you might as well get it. (I deliberately didn't pick SV/NYC. Dallas and Berlin are very similar cost of living wise.)
want to add the additional annual leave you get in Germany and average cost of the same health care in Dallas into that equation let alone the other benefits?
There is probably a point in there about shorter work days and legally mandated overtime pay, but it doesn't add up to 40k per year.
Honestly, the more I look at this, the more it seems like there are hidden mechanisms that keep pay below market value in many European countries. E.g. wage collusion and the like. I am almost certain that this is part of the picture, although there are also other factors at play. (Smaller, less homogenous markets than the US, more restrictive laws around business ownership, fewer gargantous and profitable companies that compete for talent, etc).
The High-Tech Employee Anti-Trust Litigation looks very curious to my Norwegian eyes. Cold-calling employees at competitors for recruiting is widely considered inappropriate behavior. I would not be surprised to find out that there are eerily similar unwritten agreements between large employers here.
