Who is causing the natural population growth ? Is it the child allowance, overgenerous welfare, or previous immigrants wanting large families ? And if it is an issue why are we accepting further immigration on top making the problem worse ?
We ought not need millions of new homes. The population ought not be growing like bacteria culture in a Petri dish. Human beings are expeceted to be more responsible. There's nowhere to put more houses save to more urban sprawl, and it is a stopgap measure to push the problem onto future generations to solve, anyway. The root causes are never tackled. We need zero immigration save for exceptional cases, and we need to dissuade folk already here from have more than 2 offspring.
Meanwhile, if the EU is such a wonderful place, maybe we can find loads of folk who want to emigrate there and solve the issue here.
