$30 million for mice - economic stimulus?

I am truly heartsick right now. How does $30 million for harvest mice create lasting jobs or real value in the economy? It doesn't. It might create temporary tangential work, but it doesn't create a new profitable company that produces anything. I'm so disgusted with these people. They should be able to explain to us how each "project" included in this bill will affect the economy and the taxpayer.
