"Research" is an abstraction of R&D and then some kind of basic implementation. RGO events that boost state output do exactly what you are requesting, though I do understand your complaint. Research is also abstracted in that you can only research one of these things at a time, or that you even have control over what your pops are researching. It's also interesting that technology(and RGO events) can't flow across national borders, much less your own, especially if you are running L-F.
I figure it was a design decision, considering this is how most strategy games model research.
