We could, though. Absolutely. Literally feeding all the starving people in the world would cost a fraction of the world's surplus wealth, and a briefly disruptive but manageable readjustment of global logistics. The rest of it would be costly, but still totally doable at the cost of some inconvenience for the world's top 10%.

The problem isn't lack of solutions. It's lack of cooperation on every level from individuals to organizations to social groups to nations to transnational organizations.
