In reply to wintertree:
> I have not lied. I am sorry but you still choose to call me a liar instead of explaining how I am wrong. At the worst I have seriously misunderstood what you have said, or tried to say. I have, however, repeatedly tried to help you explain yourself more clearly but you'd rather fall back to calling me a liar.
> Let's break it down.
> Rom said: (nowhere I said that the only way to raise productivity was by increasing population please quote me where I said that)
> You say that "we need" a balanced age pyramid. And why do we "need" a balanced age pyramid, Rom? Why is it "not possible" to pay pensions and healthcare without more young people Rom?
Because there is no way on earth the working age generation is going to increase it's productivity by the amount needed to cover the expenses.
> What possible reason can there be for these two statements other than assuming that we can not raise productivity other than by balancing the age pyramid -i.e. by increasing population?
I think you should be the one to justify in a logical argument why you assume that, because really there is no logical connection. It's a syllogism.
> Okay, I admit, I did take it that you were saying the only way was to import more young people as I wrote of your other suggestion of throwing old people out as unworkable. Sorry, my bad, I shouldn't have just dismissed it and claimed your only suggestion was importing more young people.
I wasn't referring to what was workable or not, I was referring to the physically possible options to balance the age pyramid. Indeed culling old people are sending them away would work, although of course if would be neither wise nor desirable. The other option left is to have some immigration, seems a better option.
> Then you say:
> So I agree with the side of your argument that says there are ways other than "more people" to increase productivity and I disagree with the side of your argument that says the only way to increase productivity is with "more people".
> Right, I'm on standby to be called a liar again. You could try telling me my pants are on fire as well this time? Or, instead of calling me a liar you could tell me what reasons justify your statement that "we need to have a balanced age pyramid" that does not boil down to "we can not raise productivity other than by increasing the population by net importing young people".
There is no logical connection between the two, the fact that our productivity won't be good enough for us to cope with the dependency ratio does not imply that we can't raise productivity, and certainly doesn't imply that raising population increases productivity. It's really basic logic but anyway I think you're just pretending to not understand at this point.
> So far I have backed away from the other major fault in your logic. You state that the demographic shift (to many old people) is not manageable and that the answer is to import more young people to balance the age pyramid. What are they going to do, Rom? They are going to get old. You have filled in the narrow bottom of the age pyramid, and it will rise up, and as those people integrate into our culture and undergo the shift themselves, there will be a glut of young people again. So we will import some more, ad infinitum - well until our temporary leading advantage over the places we take from is gone, and then we're screwed.
Sorry but this is completely wrong, it's not because you are importing young people now that the age pyramid will necessarily be imbalanced in the future. It all depends on how many kids they have. If they make just enough to be slightly below or above replacement rate like we have now amongst native in the UK then the pyramid stays balanced. Of course we can't control what will happen with birthrates in the future, maybe they will fall dramatically and then we'll have another problem to deal with, but that is a problem we could face with or without immigration.
The reality is that even current levels of immigration are not enough to compensator the problem, it just mitigates it. So we'll have to find ways to deal with it, and personally I don't except to get any form of state meaningful pension when I'm old. Looking at the numbers, it just won't be possible.
