The New York Times daily email “The Morning” for May 8, 2023 — authored by journalist David Leonhardt — includes the following:
When Democrats and progressive activists talk about undocumented immigration, they tend to emphasize forces in other countries — like wars and political oppression — that are beyond the control of the U.S. government. And these outside issues do influence migration flows. The collapse of Venezuela’s economy is a recent example. Experts refer to such forces as “push factors,” because they push people out of their home countries.
The collapse of Venezuela’s economy is clearly not beyond the control of the U.S. government, which is imposing economic sanctions on it. Likewise, wars and political oppression in Latin America and elsewhere are very much affected, and often caused, by U.S. government policy.
