The case against high levels of immigration By Peter Martin.

However, critics of this position point to the high living standards of some of the smallest and most advanced economies on the planet, such as Finland, Switzerland and Singapore, and at the low living standards in many countries with very large populations, such as Egypt, India, Indonesia and Nigeria. [...] At the same time, while returns to some may be high, the impact of this failure to invest in the future has generally been socialised - that is, the community as a whole has shared the negative impacts. [...] The scary ageing fallacy One of the arguments often heard in support of high immigration is that it is needed to ‘correct’ the changing ratio of the elderly to the young. [...] Critics of the policy emphasise the environmental impact of endlessly growing our human footprint, and how in Australia immigration is now the primary driver of that impact. [...] While a number of influential sectors of the economy are well positioned to benefit from generalised growth, the net benefits of this policy to the community as a whole are anything but clear.
