Research is very underfunded compared to the ideal. Society captures so much benefit from innovation that inventors don't so there is not enough risk taking. Government (and Foundation) funding of research helps but it still should be more. The United States funds a lot more than any other country even relative to its success. It should do more medical and energy and educational and other research. Politicians often think short term unless the voters tell them to avoid that. Perhaps the most outrageous thing is we have not raised Energy research funding to help solve climate change!
