ELI5- Why, in the 21st century, do politics still seem to be a matter of opinion? Does mankind simply lack the means to make objective decisions about the running of our nations governments, based on cold hard facts and numbers?

Politics is about the relative weighting of various interlocking value judgements, and those are rarely if ever possible to sort out in anything like an objective manner.   You can make better or worse arguments about the relative merits of defence spending vs education (or whatever), but only rarely can you objectively define one as better than the other. 

So we are stuck with subjectivity here. That's politics.
