An Australian's wealth was once determined by their employment status, the type of job they had and how much money they made.
But in 2019, there's a new five-tier measure of wealth based on how many assets you own, according to a team of University of Sydney researchers.
Social scientists Professor Lisa Adkins, Associate Professor Melinda Cooper and Professor Martijn Konings argue that simply having a job and earning a salary are no longer adequate measures of determining class.
"In the present era, where mid-size homes in large Western cities often appreciate by far more in a given year than it is possible for middle-class wage-earners to save from wages, such a continued focus on employment as the main determinant of class is increasingly untenable," said Prof Adkins.
According to Dr Cooper and Prof Konings, there is now a five-tier asset-based class system in the developed world.
