The US colonized a country and built a labor supply.

Filipino nurses have been disproportionately affected by the coronavirus in the US. And that’s because they make up an outsize portion of the nursing workforce. About one-third of all foreign-born nurses in the US are Filipino; it’s been a growing phenomenon for the past 50 years.
Since 1960, 150,000 Filipino nurses have come to work in the US. It began with the US colonization of the Philippines under the guise of “benevolent assimilation” and has increased due to a series of US immigration policies. It has resulted in a pipeline that allows the US to draw nurses from the Philippines every time it faces a shortage.
