What made the GI generation so trusting of authority?

I find this to be an interesting question. I look back upon my grandfather who, born in 1919, saw WW2 as a young man in the army. I knew him later in life and he definitely seemed trusting of civic institutions and believed that they and the people that comprised them were out to do "good" and had good intentions and acted in "good" faith. In fact, it is quite the opposite as to how I, as an Xer, see them.
