The 'Kill the Rich' movement in Joker resonates with contemporary populist and anti-elitist sentiments
This is reflected in movements like Occupy Wall Street (2011) and increasing global protests against wealth inequality
(populist = a political approach that strives to appeal to ordinary people who feel their concerns are disregarded by elite groups)
(anti-elitist = against the idea that things should be controlled/owned by the richest/best educated people)
