If you didn't become a teacher someone else would. If you didn't donate to charity there's no-one who would fill in your place. Hence, you should donate to charity and not become a teacher.

As an aside, I'd like to see evidence that teachers or social workers have much impact, even ignoring replacability concerns.

I'd also like to see evidence that Buffets don't have a significant social impact through the work they do. Successful companies create valued products, jobs, etc. and depend on investment. On the other hand, they may also make income inequality different and hence lead to less efficient allocations of resources in terms of quality of life. Anyone know a good starting point for reading about this?
