If you could remove one thing from the world to try to make it a better place for all people, what would you remove? Why would you choose that?
I believe, though i know that i will get plenty of contrary arguments for saying this, that we lived without structured inequality (i.e. social stratification) for a hundred thousand years or more with children being treated gently and respectfully, men and women treating each other as equals and very few or no reasons to make other kinds of distinctions.
Is there violence? Almost all of that would go away if humans treated one another as equals. Conflicts would consist of reasoned arguments, and if there was hunger or other deprivations they would be equaly shared by all.
There are still societies, i can hardly believe it myself, where every older woman is considered to be one's mother and every older man one's father and where every younger person is treated as one's son or daughter.
If your child asked you for bread, would you give him (or her) a stone? If you gave a child bread in the school cafeteria would you get fired?*
