This drawing is from 1917 and says it all.
The truth is America makes, and the world takes.
Americans always see the fruits of their labors stolen by greedy failed foreign parasites.
America has been invaded 3 times since 1900 by foreign parasites: 1906-1921, 1965, and 1998-present.
In every single case, the invasion led to collapse + economic disaster. In the case of the 1921 invasion it led to the Great Depression and World War 2.
History proves beyond doubt that open borders and foreign invasion collapses the US.
