Indeed you should, and you do: human longevity has quadrupled in the last century, thanks to improved government funding of science. The problem nay-sayers of such funding have, is that science works. By hook or by crook, it genuinely works. That's why we can talk in real-time across the globe, instead of waiting for a man to carry a hand-written letter across the Atlantic. That's why we can expect to live to see our grandchildren, instead of having 20+ kids to beat an appalling infant mortality rate.
Science works, our society is built on science, and we should keep the money pouring in because scientists are the only ones who understand how it works - not because they jealously guard its secrets, but because we've created a culture that doesn't want to know.
