If you are in the lucky position to have a job - how much pressure is on you today to work 10 to 12 hours, on weekends, being forced to be available even while on vacation?
the difference being what you are getting or accomplishing for 10-12 hour days. if you're taking home 15,000zl per month with 50+ hour weeks, it's justifiable.
also, let's consider your buying power after all that work. in Poland, a good salary is around 3000zl/month net for most people (my in laws, one is a cop, the other is a nurse, barely make a combined 3,000 zl/month but let's use 3,000 for argument's sake) and in the USA (I use the USA because I know what numbers are accurate and what numbers are inaccurate) an
average salary is around 3,000 USD/month net, excluding big cities where it's obviously higher. Now say you want to buy a plane ticket for $1000 to Chicago from Poland. That's an entire month's salary. For the American? A week and a half.
Time and time again, people forget to consider the buying power they have in the country they are talking about. What good is a "nice salary" if you can't buy anything with it?
My sister in law, 29 years old, has been in Germany for 10 years. As much as she doesn't like German culture or the people for that matter, she simply cannot ever see herself moving back to Poland because it simply makes no financial sense. Her entry level job out of university pays so above and beyond what she would earn in Poland to do the same thing that unless she finds a wealthy Polish guy one day, marries him and they decide they want to live in Poland, she'll never ever go back to her homeland to live.
These conversations are so silly. Nobody wants to look at Poland for what it is. I dig the place, enjoy visiting, had a good time there for a while.....but raise kids and grow old there? Oh hell no. Why do that when I have options, and options is exactly what a lot of Poles now have with the EU open border arrangement.
