As others pointed out, CoL is also way lower in most parts were there are relevant jobs to be had.
I am working a job that would pay at least double in SF. I can afford to pay the mortgage on a 130 square meter house with 500+ square meters of garden and relax by growing my own food as a hobby with 40 hours per week, 6 weeks of holiday, paid overtime, really good health care covered by insurance.
I live in one of the four largest cities in Germany. So I benefit from the infrastructure like theater, Medical stuff and so on as well.
And also the ability to start a business on the side with filling out a single form.
And I am able to generate FU money from my main salary, go on trips, give to charity and such.
Reading about insane prices for living in SF or other tech regions puts a damper on the high salaries IMHO.
But I also define my life not by the amount on my pay check.
How is that possible? When I look at typical wages in Germany (50k - 80k Euros) vs cost of houses that size in Germany's four biggest cities (800k to over 1 Million Euros), something does not add up. Either your pay is way above market rates or you got your property way below market rate.
Either way, to me at least, your situation is extremely fortunate but you're an outlier and no developer moving to Germany could replicate it in the current market conditions.
They're made up.
At least job satisfaction doesn't change, I work with startups that interest me and I get to hack on a stimulating open source project. I'm just healthy while I do it.
And the healthcare part what are you even talking about - what employer doesn't provide healthcare in tech ? You'll likely have a good plan an better coverage than NHS (eg. decent dental)
What would an NHS-style plan cost in the US? Like, I'd be happy in a shared hospital room and having lower priority for non-emergency care, but in exchange having 0 co-pay, 0 deductible, 100% coverage for everything (including long-term care), 0 ambulance fees and a maximum prescription cost per item of $12/month?
(Unless you’re in scotland and Wales where it’s just free, because prescriptions are a trivial cost)
I suggest living in the US for a year or two to see if it's the dystopian hellscape you think it is - you can always fly home to the glorious NHS if you stub your toe.
The other aspect I forgot to mention is the way work days are treated. I work 7.5-8 hour days and then I get to hack on my own stuff. I'm sceptical of US attitudes to overtime.
The customary minimum is 2 weeks but most companies offer more and you can negotiate for more.
