Following your logic how then the Poles get by?
First of all, you are not a Pole, and the rules that apply to them simply do not apply to you at all, so don't even start thinking along those lines. They have family ties that bind them to Poland, they have the home court advantage, and they have extensive networks of family and friends that enable them to save a considerable amount of money, and to help them advance in their careers.
Second of all, hundreds of thousands of Poles have been so discouraged by the lack of good opportunities in Poland, especially for young people, that they go abroad to work that they go to the richer countries of Western Europe to work. A forklift driver in a warehouse in the UK can make a lot more than a physician in Poland, for example.
Poles are struggling a lot more than their counterparts in the West. Wages are much lower and savings potential is drastically lower. The Poles that stay do so because they either have snagged one of the few decent jobs available, or because they do not want to leave their families behind. Or because they are to demoralized to have the time and energy to look for better jobs abroad.
Sorry, but you are vastly underestimating the downsides of living and working in Poland. There is a very good reason that so many Poles go to work abroad, and why so few people from richer countries come to Poland to work. There is nothing you have written that would make me think that your coming to Poland to work would not be a major mistake, again, personal and sentimental reasons notwithstanding. It is difficult for me to imagine that any personal or sentimental gain you would experience working in Poland could ever offset the huge drop in savings potential and personal advancement that you would suffer.
