I think part of the problem - here in the West, anyway - is the way politics are reported. The issues are no longer the story: the story is the political lives of the actors. Some examples:
I was at my parents' house watching the news on the telly on the Saturday before the US general election. In a report on the general election, the journalist listed about five of Hillary Clinton's policies as bullet points. My Dad said "that's the first time I've seen anybody report on what Clinton's policies actually are". All the election coverage was about "can Trump beat Clinton" and "what do the opinion polls say".
Reporting on Jeremy Corbyn is all about how incompetent he is or how much the Labour masses love/despise him. Almost none of it is about what he actually stands for.
So people could be forgiven for thinking politics is just another piece of reality TV and politicians are just another bunch of reality TV stars and it doesn't really matter what they do or how they got there as long as they are entertaining.
