Imagine a very fast running tap. At present we cannot turn that tap off and at the rate it’s running our health system will simply flood.
The best we can do is periodically regulate the flow of the tap.
Given that we are human, there are some who really cannot see the problem mate if the tap is just left to run.
Therefor, in an effort to try and keep relative peace amongst 70m people, the government has to let the tap run at different rates, all the while checking the depth of the water.
