And the irony is that as the Government have already categorically stated the number of immigrants could even exceed present levels if they deem it advantageous to the economy.this graph may explain the thinking of Mrs May's government which is beholden to the attitude of brexiters:
basically, if the economic news are bad, then the government veers toward soft brexit. The middle point for brexiters is -2.5% of their personal income. Mrs May may have to wait until we hit some substantial bad news before notifying the EU. If she calls before that, the only way is hard brexit.
That is the underlying "Elephant in the room"
Basically any sacrifice on the part of the Brexit voters will be for absolutely nothing more than Cosmetic,Illusory and temporary changes to the Status Quo.
