The Post has an article on reverse emigration; the pandemic forcing migrants who lost their jobs to return home. What I found interesting was the diagrams showing the volume and direction of remittance flows. Mexico and India were big recipients and the US and UAE big sources.
I remember in the late 50's and 60's the left was very concerned about the volume of foreign aid Western governments needed to provide to the new governments of the Third World managing their new independence from the old colonialist powers. That was a big big issue in those days. Decolonialism is about as forgotten these days as the Cold War. For a long while it seemed that the effort was doomed to failure.
Without much notice, perhaps dating back to the immigration reform in the US in 1965 and OPEC oil embargo in the 1970's, emigration grew and so did the remittances back home. Remittance flows reached over $500 billion in 2018, according to the World Bank. In comparison foreign aid was $140 billion.
I may be getting somewhat conservative as I get older, but I take this as pointing to the power of individual decisions, market driven even, more power than progressive's belief in the ability of rational government to direct the course of human affairs. It's a reminder, not conclusive.
