Yup, exactly that. Polish literary Nobel laureate Czesław Miłosz was an immigrant to the US around 1946-1950 period, and he noted that what struck him in the US was that an average American is probably 10x kinder and nicer person than an average Pole. To him, the Americans were almost like children, happy and innocent, unaffected by the horrors of this world that the Polish people were subjected to.
As Nietzche noted - what doesn't kill you makes you stronger, and Poles (and Russians, Ukrainians, Belorusians) that survived the war and communism are pretty tough as a result - but at the cost of having a crushed sprit and, quite often, losing hope in humanity.
