The world would be even further away from accomplishing those lofty goals, had they not contributed.
It'll likely take many, many generations to figure out how to balance those conditions in a way that doesn't sacrifice one of the others.
For example, how do you redistribute the wealth for the poor, without violating the liberty of the wealthy? How do you maintain the unity of humanity, without discouraging diversity? There are answers. And those answers have been improving. Those answer even talk to each other, if we've the ear to listen.
Thanks for the excellent question,
