low unemployment, huge increase in average per capita wealth, wage growth ... seems like the average Australian is benefitting at present.... Although personally I would argue that this is a temporary state of affiars, and influenced by global factors and the boom/bust cycle of capitalism at present rather than being linked to multiculturalism ...

Interesting you refer to texts written in 1917 to describe what is happening now. If you were of a different mindset you could refer to Rosa Luxemburg's arguments about the future of capitalism and also social dempcratic nations ... and find plenty of evidence to support THAT perspective.

The demography factor is a by product of a number of things, including, but not limited to, the legacy of western (european) imperialism ... in the past white westerners acted as if they owned the world. The ideologies that enabled us to develop so rapidly have been adopted by other nations who have, in the latter half of the 20th C especially, pushed more and more for democracy, and a view that their citizens were equal to us, and therefore deserving of the same rights. One of the by products of that is that many of these people have become economic migrants to our stronger economies - in the past usually encouraged by western nations who needed the labour to keep their economies growing.

this kind of fell apart on the latter decades of the 20th C, in part due to the economic cycle, resource politics and reorganisation of geopolitical boundaries.

If I were German, Falke ... one of the things I would be looking at before multiculturalism would be the impact of reunification on the German economy over the last decade +.
