Brexit, at its heart, is a recognition that Britain has become steadily weaker since it spent much of its empire wealth fighting two world wars – too feeble in the years before the 2016 referendum to sustain an exchange rate of $1.60 and €1.40, just as it was too poor to cope with $4 to the pound in the 1950s and $2 to the pound in 1992.
Manufacturers were unable to make things cheaply, reliably or efficiently enough against the headwind of a high-value currency, forcing many to give up. An economy that boasted 20% of its income coming from manufacturing in the 1980s found it was the source of barely 10% at the beginning of this decade.
Surges in GDP growth in the 70 years since the war can be attributed (and this short list makes the point crudely) to periods when there were cheap raw materials and energy costs; or a growing population; or foreign ownership and management of key industries; or the offloading of vast amounts of state and mutually owned assets; or cheap borrowing. Without these in operation to improve the UK’s performance, a lower exchange rate became inevitable.
So, the 70 years since 1945 were years of bad economic management then? Doesn’t that mean that those years of bad economic management should not be repeated? You know, that puts the kibosh on the entire Corbyn/McDonnell set of plans?
