Why has the populist right been rising across the Western world?

One thing that has been concerning me is that it seems that across the Western World (since it can be a little vague, I would describe the Western World as North America, EU-aligned Europe, Japan and South Korea, even if Korea has bucked the trend mostly as a reaction to the last right-wing populist trying to institute martial law.) that the populist right has been doing good, finding themselves either second place to liberal parties or even taking power.

How would you, as a liberal, explain this rise of the populist right across the Western World?
