God, if I could choose, I would say none. All of these lead to inequality (because circumstances vary between many individuals) but I believe prestige should hold the most weight in determining social class. Prestige (which is respect, recognition, or regard) is based on many criteria, including wealth, family background, fame, leadership, power, occupation, and accomplishments. Leadership, power, and accomplishments can both be achieved by any individual with hard work. This is still an unfair balance (gender inequality, racial/ethnical inequality/racism) because of individual factors, it still leaves hope for some people to rise the social ladder.
We just opened up and are doing 4 stages of slowly opening things. I’m personally still terrified to go in public bc I know it’s not open bc it’s safe it’s open because the government cares about money more than human lives :) our graduation is postponed till next semester.
