Another somewhat unexamined perspective  is to focus on what happens when the bipartisan elite consensus fractures. Looking at the Trump and Brexit phenomena, rather than honing in on the lower rungs of the socio-economic ladder which have been displaced by globalism and automation , it may be more instructive to interpret what has happened in the US and UK as radical splits from within the ruling classes. One faction of those classes, itself threatened by the rise of China and by the demographic changes wrought by mass immigration reached out to the masses and, with skilled evangelists(Messrs. Trump and Farage) wrested power from the majority view. Worth re-reading C. Wright Mills' "The Power Elite".
