Is it morally wrong for university students to not have summer jobs?

No. Not unless you are expected to get one to help pay for student loans and you don't get a job just simply because you don't feel like it. Otherwise, while most students do have summer jobs to help pay for student loans, tuition, books, fees, etc.Or just to have some spending money, having a summer job is not a requirement.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
