Moving here to Poland was probably the best decision in my life
A sentiment I share. I had a wonderful time in Poland. But I am highly qualified and experienced, and had cash enough in the bank so that I did not have to worry. I had NO competition while in Poland, and was able to name my price, or afford to be generous, just for fun. And I speak the language, and went to great pains to learn about the culture.
I can therefore only recommend it.
That's a non sequitur. I can recommend it only to a select, and small, subset. For most, it's a lousy option. Especially when so many better options exist. And they do.
Think of the poor Indian student who realizes that he just got suckered into paying his parents' life savings for a degree that will qualify him for washing dishes or cleaning toilets.
Or of the poor Indian engineer who figures out that he is earning a quarter of what his colleagues who "shifted" to richer countries are making, as would he if he had done a proper job search.
I doubt anyone comes here to save large amounts of money
quality of life
For an expat professional, quality of life is virtually synonymous with savings potential. Everything else is window dressing.
