My 2 cents worth,
I finished my schooling at 17 and had School Certificate.
Qualifications don't really mean a lot over here, just a willingness to learn new skills and having the right attitude is what matters here.
On the subject of being labelled as Blue-Collar, I suppose I am, but at the same time, we wouldn't be still going into peoples homes if we were as boorish and nasty as the stereotype suggests.
One thing that I am particularly proud of is the fact that, if I have a small DIY job to do at home here, I can do it and will not have to pay someone else to do it!.
