Re: Nothing economically beneficial will happen until the Tories get kicked out.
As I said above, even ignoring immigration our population has increased because we're living longer but birth rates are falling. That means that the demand for services increases whilst the population supplying those services is shrinking (extending retirement age is unpopular). Household numbers are also increasing because there are more adults living singly.
Whatever your political inclinations those are the demographic trends you have to work with.
What's your solution to balancing those supply and demand factors?
