Seems like it's only "free-range parenting" if you've got serious funds, otherwise it's plain child neglect.

I agree with this. Rich kids roaming Europe is normal. Poor kids fending for themselves is neglect.
This. If a working class single mother living on a council estate was to let her 15 y.o. CHILD go abroad with their mates with NO ADULT SUPERVISION, she would be lambasted, and probably have her children taken away from her.
But when it's middle - and upper class families, it's OK somehow. 
Even so, I don't know one single parent who would allow their 15 year old CHILD go abroad with their teen mates - with no adult supervision. And I mix with working, middle, and upper-class people. It really is irresponsible and careless parenting!
ALSO, it's utterly ridiculous to say a middle-class 15 y.o. boy will automatically be more smart and mature than a working class one. Some people on here sound like they lead very sheltered lives, along with being very narrow-minded.
