Most of the richest 1% would come from few different countries, so there would probably be less cultural differences at least. I could imagine the world being divided into one country per continent or something. People living very far from each other would accelerate digitalisation of governance.
Cutting emissions by about 95% could also help with climate change. Also people could just move away from highly affected regions.
I think humanity might just be better off. That said, I dont think this is limited to the richest 1%, most distributions of 1% of the population would do.
