So, is anyone interested in my theory as to why our western politicians will constantly allow never ending increases in immigration (illegal or legal) no matter how much the majority of the citizenry may oppose it? It really is quite simple... our economic system (and our political system) is based upon capitalism - and capitalism is on its last legs (dying a slow death). Capitalism does not seem capable of providing any real economic growth to our socieities any more and Capitalism needs growth to function well (and to justify itself). Ergo, one percent addition to the population by immigration produces at least 1% growth in the economy and this is apparently critical to prevent deflationary cycles. Now if capitalism was half as robust as everyone likes to think, then we wouldn't need all this immigration (legal or illegal). Indeed, in the case of the USA, the political limits on legal immigration are the primary reason such a high level of illegal immigration is permitted. In Canada, we don't need such high levels of illegal immigration because we allow very high levels of legal ones. Ultimately, capital doesn't care if immigration is legal or illegal. And yes, rising birthrates can provide this 'boost' that capitalism needs but it is not apparently available, thus immigration. And this has everything to do with the failing rate of average return on capital. We're down to single-digits now and still apparently falling. On this basis, a far smaller percentage of profit is available for re-investment (as a comparatively higher proportion of profit is 'returned' to the capitalist with the falling relative amount of profit available to any given capital enterprise).
