Maybe the disorientation that many people experience as a result of globalization, makes them yearn for a life that reflects the security of their past, breeding nostalgia.
Maybe that inability to cope with a rapidly changing world order is what fuels the insulatory mechanisms of right wing politics of today - making America Great, Brexiting, building Hindu-rahtras and Islamic Caliphates.

Clinging to the past is just fear of an uncertain future.
