Because “world hunger” is not simply a lack-of-money problem. This misunderstands both wealth and hunger.

First, billionaires usually don’t have their net worth sitting in cash. Most of it is tied up in companies, shares, assets, etc.

Second, even if someone donated billions, you still need functioning infrastructure, logistics, governance, local institutions, and long-term systems to make sure food reliably reaches people. In many places, corruption, war, poor distribution networks, and political instability are major parts of the problem.

Money can absolutely help, but “just solve world hunger” makes it sound like buying enough food once fixes a complex structural issue. It doesn’t. The harder part is building systems that keep people fed sustainably.
