Well a quick multiplier of 1.35 means $135k in USD yearly for a 6 figure salary. Well that's a rarity even for software developers here in US unless you are pretty darn good. BTW, how much is the average salary paid by american companies in Europe ?

Speaking as another European who has always been put off by the usual American conditions, money is not a very big concern to me beyond my (admittedly quite frugal) standard of living. Time is a far, far, far more important resource, and working in the USA seems to include insane hours and constant overtime and few vacations.

Also, I think you don't need that much money in Europe, thanks to things like socialized healthcare.

My time on earth with the ones I love, is more important than money.

Not really. In many EU countries it is about 3x of average salary.

living costs are much lower though, at least in the parts of the US where 100k are common. besides, what do you count as 'salary'? companies pay into the 401k and the social security, doesn't show up in the salary though. and they pay quite a bit depending on the actual salary.
