QotD: The "favourite weapons of Imperialism": "protective tariffs, prohibitions of imports — limitations on emigration and immigration. This is becoming more significant now."

"In the last decades of the nineteenth century, and the first decades of the twentieth, the favourite weapons of Imperialism were commercial weapons— protective tariffs, prohibitions of imports, premiums on exports, freight discriminations, and the like. Less attention was paid [then] to the use of another powerful imperialistic weapon — limitations on emigration and immigration. This is becoming more significant now."
~ Ludwig Von Mises, from his 1922 classic Socialism: An Economic & Sociological Analysis
