It is curious that this forced child emigration occured shortly after World War II: we appeared to have replaced discrimination by race by class and wealth discrimination. It seems even now one's OK but not the other,although I find it difficult to tell the difference.
I suppose an apology when some of the victims are still around may help some of them but it's coming from someone who had nothing whatsoever to do with the dreadful policy, so is quite empty. Apologies seem fashionable at the moment but some - such as apologising for the Crusades - are really silly and pointless.
Compensation is not on offer in this particular case. Should the Government pay compensation for acts of long ago.To some extent it depends who's on the winning side. Anyway the Government doesn't have any money so they would tax the people who had no part in policy making now or then. Perhaps the descendents of those who profitted out of say the Slave Trade should pay any compensation - their wealth in still around and in high places.
