"Fuck you got mine" is the attitude of the boomers expecting young people to die for a country that the boomers left economically and demographically ruined. Young Germans have the worst life prospects of any generation in the past fifty years.
You're discussing boomers in the context of an awful lot of history.
But if you look at serious polls then not many young people will actually fight for this. I remember reading a number of around 15%... And those probably don't have a high IQ.
