Life is Unfair
I think equality is an illusion. People will anyways treat each other with contempt over the pettiest of things. Whether they're from a different country, state, city, or neighbourhood. There will always be anger. Men will always have opportunities women will never have and vice versa. There will always be a ruling class and a poor class. There will always be people who can't catch a break and there will be people who will have everything handed to them. Though the roles may reverse.
We can create opportunities for everyone with quotas for every race, gender, etc. Though that will neglect those who probably deserve the job the most and your value becomes what group you belong to rather than who you are as an individual. We can make everything purely a meritocracy and only the most deserving people get the job. Then we neglect those who may need it the most or neglect those who never had the opportunity, to begin with.
I don't know what the answer to inequality is or if there is even an answer. Because ultimately, no matter what we do. Life is unfair.
