Two wrongs don't make a right... The other questions should be corrected IMHO.
Tags apply to the topic of the claim. The food aid claim is not about politics, and not about about a business practice. It is about a claim regarding charitable donations to Africa and their supposed effect. We need to be careful that politics and business do not become meta tags.
Stretching the meaning, we could use economics. However, the claim is not necessarily about the economy, but the overall effect. It is more of a "freakanomics" topic than classical economics.
I don't think nutrition is appropriate at all.
Finally charity should redirect to charities.
- I've retagged the questions (your question correctly shows the old version)
- I've added they synonym - hopefully that's not controversial
- I've closed one question from May '11 that was off-topic to today's standards.
