Obviously, we can't fund everything in physics. There has to be a selection process. Who should make the decision? Should it be based on opinion polls of the public? I think the decision should be made by physicists. Most physicists would say that cold fusion is "fake physics" but mainstream fusion research is legitimate, and worth funding. If you left it up to opinion polls, the public might decide to fund cold fusion but not mainstream fusion research! Physics is different than other subjects, including other fields of natural science. A member of the public who is not a biologist can form a well informed opinion about whether the government should fund a program to identify specific genes within the human genome. A member of the public who is not a physicist can not form any opinion whatsoever about whether the government should fund a program to look for neutrinoless double beta decay. Physics is uniquely inaccessible to the public which can not evaluate the relative merit of various physics programs. The public should support government spending on physics in general but should not be involved in picking and choosing which specific physics proposals should receive what funding. It should be based on process similar to referees or peer review.
