I find the inclusion of Reaganomics as a 'kind of math' quite entertaining. Anyway, if the speaker was trying to promote the study of mathematical methods and discoveries in other cultures as a field of cultural or anthropological inquiry, then I'm all for it. But if he's trying to equate them with Western mathematics in terms of usefulness (or merit) - that is he wants them promoted as mathematics as such - then he's out of touch with reality. In a big way.
