you can see the same in 1700 BC when technology of better shipping enabled vast commercial links between Egypt, Crete, Myceanean Greece, Anatolia, the Hittite empire, Assyria, BAbylonia, Elam, the Indus Valley
you see it also with the better ships of the europeans in the years 1400 to 1700, then steam ships etc.
The US was the foremost proponent of globalization in the 20th century as the US after WWII was the only real manufacturing power and needed places to sell to. Globalization is nothing more than an expansion of the initial trade between city states.
You (literally) can’t say that politics has had nothing to do with it and will not have anything to do with it in the future.
Tariffs are as old as trade. The USA built its manufacturing base behind steep import tariffs. Up to WWII the Republican was known as the tariff party. Alas we gave away the store. Globalists are not patriots.
Bull. We offshored factories to exploit cheap labor and maximize profits. The fact the globalist lowered our trade barriers to extremely low levels made this all possible. This put Americans workers in direct competition wit the 3rd word .It was nasty and cutthroat and the political ramifications are coming home to roost.
