This letter gets posted time to time. Definitely one of my favorites for explaining the rationale on spending money pushing boundaries when there are plenty of things that money can do to help people in need now.

Investing in space exploration is necessary and all I don't disagree. But saying it adds to the economy as much as investing in people who need investment I can't necessarily equate. There's millions of children's not getting an adequate education, and there's millions of people hungry and starved. In our current society; investment only happens when there's a vacuum of opportunity that could be filled. Only governments seem to invest in people right now. In a space faring society education is necessary. We don't have enough highly trained workers as is without space ships. We need investment and radical change in education.
