In western Europe you'd just have to specify the availability requirements and they'd do it there as well. You'd just have to pay for it.
Edit: If you pay someone 150k€ in Germany what they see after-tax is just not that much. They are going to compare this with the 9-5 IGM position (when it is available...). Why not just admit that you don't want to pay equivalent wages for accessing the western european market?
For Germany this in not true, I have direct experience of this. Your income is really high at 150k€, even taking in account all taxes you pay if you’re self–employed (plus insurances, social security contributions, etc). You’re way above what you would get from the German market, unless you go into management.
Is it his responsibility? If some countries have a better tax policy, why should he not take advantage of it, and ultimately end up in a situation that benefits both the employee and his company?
If you are actually talented, have a good work ethic, and the track record to show that then get a job that relocates you to London.
That is your only option if you want to stay in Western Europe as a SWE long term.
This is terrible advice. Source: been there, done that (worked my ass off to waste half my TC on taxes and the other half on cost of living). I ended up moving to a low-tax Eastern European country so I can actually feel like I'm being fairly compensated for said talent and work ethic.
I don't actually see how your advice improves the situation - the net disposable income you'll end up with is about the same you'll have from being lazy in Western Europe - except at the very least, some Western European countries are actually nice to live in. If you're gonna be poor anyway, may as well be poor in a nicer place.
Then you're going to have to pay, aren't you.
Money ain't a problem, attitude is.
The Western Europeans with the right attitude either move to America (eg. I'm sponsoring the O-1 of 2 founders who are shifting from London to SF for that reason) or end up becoming leadership for American companies in Western Europe.
And even though I could easily move to London (modulo family) I wouldn't as the wages there are much worse for my specialty.
Honestly based on talking to friends and former colleagues I think you're probably underpaying for many Western European markets, TC of 200k is where it's at now.
I'll leave your attitude comments out as I don't have enough context to reply effectively.
