Perhaps, Barry, what is needed to suit your own peculiar needs is for the implicit to be made explicit, and that a statute should hit the books formalising, "One law for the rich and another for the poor."
In your own drive to tempt the wealthy of drought stricken foreign pastures to luxuriate themselves within these shores you neglect to account for their accompanying caravan of lesser mortals.
What legislation do you mean? The Human Rights Act, or one or more of the many treaties our elected representatives have signed in the course of our membership of the EU?
You can blame who you wish, be it Plato for his Symposium*, or Adam and Eve or the great prophet Zarquon**. I suppose it all depends on how difficult it has been to shift the blame in the past.
