If that is so, why are people from the middle east and Africa risking their life to reach central Europe and northern Europe, instead of going for eastern countries like Poland?
It is not only there is a real threat because of the Russian invader to start a war against neighbor countries like Poland and other eastern countries, but also, we could say northern and western Europe has more tolerance to embrace people from all over the world and be open minded with immigration and allowing good working people to start their new life there, instead of refusing entrance to them into their republics. That is a good reason why many people in my country have decided to move to Central and Western Europe instead eastern Europe.
It is not only about finding good places to live, but also societies which are willing to open up their arms to help others, in some ways.
You are right - Western Europe is seen as more accommodating to immigrants than Eastern Europe. Also, Western European countries are generally wealthier than Western European countries, so they are thought to provide more benefits to immigrants. I believe the standard of living of Eastern Europe is high by global standards, but not as high as Western Europe - though this may change in a couple of decades. It seems that Western Europe is seeing an uptick of violent crime lately.
