I watched an interesting feature about the flakey British film industry tonight on BBC 4. As you’d expect, it was mostly whinging and hand-wringing from all sources ? hyper-interventionist culture-boosters and laissez-faire populists alike. The giant lacuna was the glaringly obvious fact that the British film industry is hopelessly held back by an economy about a sixth of the size of the mother of all markets ? the USA. Outside the scope of the programme was the equally obvious conclusion that we desperately need to boost the overall size of our economy (both here in the UK and in the wider EU). Governments of all complexions have been trying this without success for decades, naturally, so this represents a great opportunity for a Government ready to try something new. Macro and micro tweaking are not working. For a hundred years, the economies of the West have grown at roughly the rate of inflation ? effectively zero growth.
The American example shows us that what we need is a really serious boost to the population itself – more bums on seats, more contributors to the media economy, more warm bodies creating value. Look at Japan: twice the population on about 50% more land. A simple calculation suggests that Britain could easily handle about 100M people. Not enough to challenge the US directly but enough to lift us out of the third division and, possibly, to give us access to the kind of doubling effects that drive the US economy. Remember, recession or not, the US economy is just getting bigger and bigger and this is in large part because the inward movement of people keeps the economy growing ahead of its structural rate. Large economies grow faster than small ones and, the faster they grow, the faster they grow ? if you see what I mean. All of this seems academic right now but the evidence is mounting that US population growth is accelerating while the European population is going into reverse (while already vast Asian economies mature and compete better). Old economies ? like ours ? will shrink faster and faster. Irrelevance beckons.
So how do you grow the population of a small country whose birth rate is already behind the replacement rate? You encourage immigration. Britain happens to be the focus of interest for migrants from a large swathe of Eastern, Central and Southern Europe. Who knows how long this popularity will last? Precedent suggests that it won’t be for long. Only fools would refuse these eager migrants entry. Only lunatics would actually deport them.
