Because Germany has good living standards in many cities and salary is not as bad as you indicate.

I would consider moving to Germany before considering the UK. I certainly wouldn't ever move to the US.

The only place you mentioned I would rank above Germany is Switzerland.

Well, if they get job at these better places, its great. For others(and there will be a lot), it may not be bad option.

Better health care. Less Trump and Trump-adjacent. Lower chance of having your kids shot at school. An actual culture instead of whatever capitalism wants to shove down your throat. Unions that work. Way better transportation in big cities. Soccer teams that people care about. A few trainrides away from a holiday in Greece or Croatia (or France, or Norway, et al).

Wait until you move to Germany and hear about Osterreich (former east germany communists) - a lot of them are heavy supporters of Putin and russia in general and hate immigrants just like trumpers do. There are like hundreds of thousands of ex-USSR emigres who still love russia and support it.

regarding the rest - with german pay you wont have money to travel across Europe. your best bet will be "backbacker" style travel on budget - which is hard to do with kids.

and dont get me at the quality of their daycares....

Do you maybe mistake Österreich (Austria) for Ostdeutschland (Eastern Germany)?

And Germans have plenty of money (and vacation days) to travel across Europe, in fact you will encounter them pretty much everywhere.

The quality of care in German daycare centers is still not great despite recent improvements, I'll give you that.

>a lot of them are heavy supporters of Putin and russia in general and hate immigrants just like trumpers do.

Unlike in the USA, these people in Germany don't get their insane voices boosted by the ballot box equivalent of Affirmative Action (aka the Senate and Electoral College). Their views have remained far from the PM's office.
