The ideal scenario would be for a white male student to find out about the event beforehand and come prepared. When it comes down to only the white males not getting any sugar from the communal pot, the prepared student pulls out a whole bag of jumbo marshmallows and shares them generously with his oppressor oligarch buddies.
"Eat yours nice and slow," they'd tell the oppressed minorities. "You gotta make 'em last." Then they'd pop another marshmallow and say to the instructor "Hence the difference between a socialist economy and private industry." And they'd pop another marshmallow.
It’d be even more fun to bring the colored marshmallows...
