Will you care to share those experiences?
Boss 1: Canadian passport, two children. Worked as a marketing manager in a company, owned a house there, came back in his mid thirties because growth was very difficult there managed to come on head positions wherever he went here even as a CEO once.
Boss 2: Worked in IBM, returned in a totally different role here found the financial freedom significantly higher here.
HR guy: Had a US citizenship returned here and now working in Dubai. This was a cool guy, had personality looks and youth going for him. I asked him why did you come back? he said life there isn't a bed of roses, you gotta wake up at 4-5am to make the commute because you are in the suburbs. You spend the day at work often going into long sittings and return home to nothing but the bed. Only on the weekend you get to party like no tomorrow. But theres a constant working for the cash machine feeling. His biggest qualm was the 4 hours of commute everyday, he said that's lost time that I am never getting back that one could have spent with their loved ones.
Guy who returned from Germany: 2 daughters, earned 100k euro a year and said most of it went down in tax leaving him with little to nothing. He returned because he believed he could not raise his daughters there properly anymore and there was more money to be made here in real estate than his real estate work in Germany.
Phupa with US citizenship: My phupho had passed away, so his young daughter was about to hit high school I believe and he came back with her leaving two of his sons who are dependent on him back there because he realized there was too much at stake and since young minds are impressionable and no wife to look out for the daughter he has thus returned. Has a government job here so he can manage.
If you want to understand how and why life in the US is not a bed of roses, I suggest you watch Michael Moore's 'Who to invade next' documentary and then you will know how so many other countries are way better.
