You don't know what you've got 'til it's gone

Viewed in a global context Brexit is very much a sideshow. However, it is all part of a global backlash against the status quo which is perceived to have acted against the interests of citizens in the developed world. Nowhere is this more evident than in the actions of the Trump administration which earlier this month imposed higher tariffs on the first $34bn worth of imports from China and threatened to escalate still further, thereby risking Chinese retaliation and a further step on the path towards a global trade war. The biggest danger in all of this is the prospect that the current global economic architecture could well be jeopardised, which may not be perceived to be a problem in Hicksville USA or Smalltown England, but might result in turning our back on the most successful period of prosperity generation in world history.
To put some figures on it we rely on the database put together by the late Angus Maddison which looks at very long runs of GDP data. Measured in real terms, the increase in world GDP between 1950 and 2000 outstripped anything seen in the previous two millennia, rising at an average annual rate of 3.9% versus 0.2% in the preceding 1950 years (chart). The same is also true of the US, although its most rapid growth occurred during the early years of the industrial revolution. Nonetheless, average US growth of around 3.5% per year between 1950 and 2000 compares pretty favourably with the 4.4% rate recorded during the nineteenth century. Growth is not everything, of course. When comparing living standards, what matters is the absolute level of income. Whilst it is true that US per capita income growth has stalled over the last decade, the US still ranks ninth in the world behind three oil-rich Gulf states, four smaller European economies (Norway, Luxembourg, Switzerland, Ireland) and Singapore. For the record, Chinese real income per head is just 23% of US levels.

It might suit some American politicians to claim that their country has never had it so bad, but the US is still a pretty good place to be. The US has attained these lofty heights, thanks to an exceptional period of technical innovation – which it drove – and a huge rise in world trade which allows it to buy products more cheaply from other parts of the world, thus allowing American citizens to spend their excess income on other products. Whilst it is true that China is closing the gap with the US, per capita GDP growth has recently slowed to an annual rate of less than 3%. At current rates, it will take China 55 years to reach current US  levels and assuming China is able to sustain a 2.75% growth rate way out into the future (which is unlikely) and US incomes grow at 1% per year, it will take the better part of a century for China to match US living standards.

Worse still, the US Administration appears to have no concept of the gains from trade. As The Economist put it a few weeks ago, “Trump appears to see the world as he saw the New York property market, a place of screw or be screwed.” China may be stealing US technology and engaging in sharp practices to ensure that the playing field in the Chinese market is far from level, but that does not mean that the US should cut off its own nose to spite its face. Adam Smith – a hero of many on the right – argued in his 1776 publication The Wealth of Nations that all nations would gain simultaneously if they practiced free trade and specialized in accordance with their absolute advantage.

The US may no longer be the world’s primary producer of traditional industrial products such as steel, but it is still the world’s most technically advanced nation which in the past 20 years has given us Facebook, Amazon, Netflix and Google (the so-called FANGs) which also happen to be the largest global companies by market cap. Moreover, many companies rely on outsourcing production to external markets, and retaliation in response to US actions would imperil global value chains and force a rethink of how companies operate across borders with unanticipated consequences.

But rationality is not the order of the day. Western historians will probably look back at the first two decades of the 21st century as a golden period punctuated by a severe crisis that prompted irrational policy choices. They do say that you don’t know what you’ve lost until it’s gone. I miss the good old days even before they have ended.
