Poverty: Same thing for any people of any race the most important part is their ability to get an education that’ll get them out of it while having stability, slavery has nothing to do with it.

Whataboutism. Black people are poor exactly because they descend from slaves. When the slaves got freed, most of them were destined to poverty, and poverty is inherited under capitalism.

Australia: I live in Australia what are you talking about?!

About all the aboriginals that went through genocide, both physically and culturally, for about 200 years?

Of course schools teach in the language of the country they are in do you expect them to teach in 5 different languages?!

Yes, monolingual countries are mostly a thing only in the western world. Most of the world is multilingual, and it has been for most of human history. And there's a big difference between having a lingua franca and being dominated by a colonial language.
