There is an old 'Arabian Adage' which states that :-
"If you allow a Camel to put his 'Nose' in your tent,
he will soon have his 'Arse' in your tent and the tent will soon be unfit to live in"
(actually it says that the 'Tent' will be soon be covered in shite)
I think we have allowed the 'Camels' to reside in our 'Tent' for too long now and THEY should be forced to clear up their own mess and make restitution for that which they cannot clear.
Only fair really, considering the fact that they have become so well accustomed to living in the mess THEY have created. (imho)
