Trump's Budget Director has commented wondering if the Federal government should support research at all. In many people's view, if research is valuable then companies should do it and monetize their research. This is a clear example to the contrary (and I think there are many other great examples) of research performed by the World Health Organization. 

Companies do not find 3rd world health problems a sufficient incentive (some do get federal funding to work in these areas). And yet, Ebola is a disease of sufficient virulence to be a possible national security threat. Government research acts when the capitalist market does not, for the betterment of all.
