htere's a bid reason whu populism is surging everywhere in this world:

educated elite's "condescending" attitude or impatience towards the massive un- or under- educated, this is not helping social tolerance or compromise.

trump is likely to lose, but the voices behind him are not going to lower, polarization might turn worse.

beating trump is good and relatively easy, but his supporters can't be ignored, their anger and concerns must be addressed.

likewise in china, bo xilai was dangerous (xi is a mild copy of him), good to lock him up, but he was wildly popular in chongqing. again it's the less educated, relatively poor social class.

don't ignore them, don't leave them behind, address their needs.
