The use of low-paid throw-away migrant labor in agriculture has spread around the world. Covid-19 has made many of them suffer more, but it will do nothing to improve the way agricultural workers are treated.

Giving them better treatment, including better pay, will make food more expensive. But that will be a good thing, if the wealthy countries support poor people better. It will make agricultural jobs good enough that citizens will work in them, and make farming more profitable in poor countries so that not so many people will be desperate to migrate for work.
