Use of the term "working class" bothers me, since, IMHO, it is ill defined (for example, is everyone on this forum "working class"?), but, otherwise, I would agree. I think the "scapegoat" can be any readily identifiable group, it does not have to be foreigners/immigrants, those of a different Religion (say) will suffice, but, generally, foreigners/immigrants do fulfil the need to be "readily identifiable".
Foreigners and immigrants of certain ethnicities are. Others pass unnoticed, even the criminals.
