Been seeing people talking about food shortages here and there, like flour for example. A lot of the issue seems like the "last mile" problem rather than an actual shortage. There is plenty of food, but the human labor required to process and distribute them is in short supply.

This was a problem in S Korea too. Farmers couldn't get their product to the market. Restaurants had supplies languishing in the refrigerator. Closed school means no school lunches to serve.

The gov't stepped in decisively there as well.

One example was Gangwon-do governor Choi Mun-sun, who led an online campaign to sell his province's potatoes at steep discount while providing the infrastructure to package and ship the potatoes. It was a wild success. https://qz.com/1819670/south-korea-rallies-to-rescue-potato-farmers-hit-by-coronavirus/

Another example is the government simply buying them and handing out to people.

Remember all those care packages that the various levels of S Korean gov't are handing out to self-quarantined people? Those nice fruits and grains? It's also a stimulus program.
