I Think its B. Sorry if not right..
Although this is a broad generalization, it is farily accurate. The 1950s were an incredible stable and thriving period for the US, as people returned from the war with higher spending power and nice suburban homes. The 60s brought a "counter culture" that tried to upset this norm.
I think the correct answer would be: Lowing paying; High Paying (First blank would be High paying) Because people had risked their lives, and had come back to joblessness, and they deserved it and the warriors of today continue to deserve their GI benefits.
I hope that helped! c:
