Why science is important to everyday citizens?

Since the election, I have found myself wondering fairly frequently “What is the role of a government?” Answering this question will lead to the ability to answer other questions, like should we fund healthcare/unemployment/social safety net, and should we fund science?  I’ve mentioned before, that because scientific advances are often not immediately profitable, but rather, scientific discoveries now can lead to changes that we all use in the future. Knowledge is great! And addressing the problem of fear of/disbelief of science is going to really hurt us, now and down the road.
