The term 'greedy ones' can refer to three different types of people: misers, HOGS, and PIGS. Misers are people who are excessively frugal and hoard their money, often to the point of being stingy. HOGS are people who are excessively greedy and selfish, taking more than their fair share of resources. PIGS are people who are gluttonous and consume more than they need. All three of these terms refer to people who are excessively greedy and selfish in their behavior.
