> realizing that not all fields of research merit the same amount of funding
Unless america does it _very_ different than the rest of the western world, this is already the case. STEM research receive way more public funding and have way more PhDs than other fields, in my country it's almost two order of magnitude (this has to do with the cost of instrumentation mostly, but not only).
On the "science have turned political", yes, but that has always been the case. You can be political and non-partisan. UNSCEAR has been political from its creation, but is still non-partisan, anybody can use its research to make partisan proposition on nuclear. Same for WHO, it was _obvisouly_ political, advanced the interest of the first world in poorer countries, but it stayed non-partisan. This is probably the same for any medical research: obviously what is researched is political. Non-partisan though. Just because heart attack research was done by, with and for men, women also benefit from the research (although to a way lower degree until like 2010).
The only counter-example i can think of is the GIEC group3. I don't think it is partisan, but i can hear arguments that say that it is, and debate. But it has the lowest amount of funding of the 3 groups, and Group 1 and 2 are not partisan at all.
