I'm sure it's not the whole story but I think it's reasonable enough to assume it will be a contributing factor for many.
I have never heard of peer pressure being a contributing factor in unemployment, does it work for employment, too? Cuz maybe that would make it a confounding variable.

I think the idea that unemployment may be socially transmissible to a degree is pretty reasonable. Part of the fear of unemployment is fear of social rejection, due to negative views about unemployment. If others in your peer group are unemployed, that component of the motivation is ameliorated. There are other, stronger, motivations to be employed of course. But it's an effect I would expect to see at the margin.
And yes, I would absolutely expect it to work for employment. I see nothing confounding about that.
WTF. I wouldn't spend too much time defending this if I were you.
