why do marji parents find her request to play monopoly humorous?

Marjane’s parents had been in the streets all day supporting the Marxist revolutionary forces. When they return home, Marjane wants to play “Monopoly,” a board game that symbolizes Western children’s indoctrination to Western capitalist values. It is a humorous situation but, by the end of the chapter, Marjane begins to come to a nascent understanding through her mother and father’s stories of why symbols of capitalism, such as the game, are looked down upon in her household.This is very ironic considering the backlash against Western values going on in the country.
