(or "sovereignty" or "traditional culture"). Those for and against globalization shouldn't be surprised that change (whether it's good or bad in the long run) is often met with resistance.
The US has had more immigration than almost any other country, but we've had anti-immigrant movements for just as long-probably peaking with
Know Nothing movement of the 1850's, the (republican)
Chinese Exclusion Act of 1882 and (the republican)
Immigration Acts of 1921 and 1924.
Even the
Great Migration of African Americans from the South to the North in the early 1900's caused a great deal of social instability there because Northern whites were not used to living with such large numbers of African Americans. Big change caused friction. Doesn't mean that the change wasn't good in the long run, but it did bring with it big problems.
The real question is not whether globalization causes friction and pain to some degree. Obviously it does. And obviously the history of nationalism also shows a large amount of friction and pain. (One of the reasons that Europe decided to shift the focus from nationalism to cooperation after WWII.) The real question is whether a world based on globalization or on nationalism (or some delicate balance between the two) is better for everyone.
Since WWII it has been liberals who have pushed globalization and conservatives who have fought it. This is particularly obvious in Europe today where liberal governments promote immigration and a strong, borderless EU, while conservatives oppose both.
But liberal support for globalization has been almost as strong in the US. FDR and Truman made it a point to create multilateral organizations like the UN, GATT, IMF and Brenton Woods to make sure that the world didn't go back to the high tariffs, border controls and an ineffectual League of Nations that existed in the 1930's. FDR repealed the Chinese Exclusion Act and negated the tariffs put in place by Smoot and Hawley. Kennedy started and Johnson finished the
Immigration Act of 1965 which repealed the republicans' 1924 Act and greatly liberalized immigration laws.
Modern American conservatives have embraced globalization more than their European counterparts, but even their embrace only extends to trade and economics (and even that is opposed by the teabagger base of the party). When it comes to immigration and culture our conservatives go back to their roots of 1882, 1921 and 1924.
The conversation we should be having is about where the best balance is between globalization and nationalism, how do we get there and how fast should it happen.
