Koko- my take, as an American, is that the term 'blue collar' refers, largely, to type of JOB. My take, again as an American, is that the term 'working class' refers to class/caste. I guess you could extrapolate that a 'blue collar' worker is from a lower socio-economic class than a white collar worker, and that is all tied into education and opportunity that could go hand and hand with a class distinction. I don't think that is so, but it could be seen that way.

It was interesting to read Miss Z's post, and decriptive terms, as an American. I don't think I recognize the class distinction that seemingly exists in GB. Here, in the US, there are plenty of class-less, high class (based on income) people!
