Stansgran, should children with financially challenged parents be punished (this has been discussed in many other threads). The whole school goes away, bar one or two, with the other children pointing the finger? Often the children of immigrants, who would particularly benefit from the experience (as their parents are unlikely to ski) to bond with others?
Of course there are occasions where you think - he they cut down on the fags and beer, they might be able to afford it, but generally, in my experience, the help is given discreetly exactly to those in need here.
I went as a helper with the primary school from the village to a Bird Park in nearby France last year. Camping overnight, with the WHOLE school, just one night, but with all the little 4 year olds - not a tear either. Entirely paid for by the Council and local Gvt and fund-raising- and everyone the same- wonderful.
