Trump has turned his back on the foundation of US economic might - the fallout will be messy

The height of this wall needs to be put in historical context. It takes the US back a century in terms of protectionism. It catapults the US way above the G7 and G20 nations into levels of customs revenue, associated with Senegal, Mongolia and Kyrgyzstan.

What occurred this week was not just the US starting a global trade war, or sparking a rout in stock markets. It was the world's hyper power firmly turning its back on the globalisation process it had championed, and from which it handsomely profited in recent decades.

And in so doing, using the equation that underpinned his grand tariff reveal on the Rose Garden's lawns, the White House also turned its back on some fundamentals of both conventional economics and diplomacy.

The great free trade debate

Trump talked a lot about 1913 in his announcement. This was a turning point when the US both created federal income tax and significantly lowered its tariffs.

Before this point, from its inception, the US government was funded mainly by tariffs, and was unapologetically protectionist, based on the strategy of its first Treasury Secretary Alexander Hamilton.

The basic lesson the White House has taken from this is that high tariffs made America, made it "great" the first time, and also meant that there was no need for a federal income tax.
