As one of those white collars in Poland, I think some of that hesitancy against defending your country is because current ruling party seems very anti-intellectual and it seems like a lot of country supports them, so intellectuals think "If they wan't tnis, let them have it with all the consequences". Me: I'm preparing to defend my country, but it's no use if I'm just sent to meat grinder by incompetent politician-ass-kissing generals.
