I am sure West Africa can come together and offer land to descendants of slaves free of cost.
Best apology in my opinion ain’t just words.
That will never happen. There are certain tribes(like the Ga outside Accra) that are pretty possessive on who owns in their traditional populated areas. Giving away random land to foreigners will not be received lightly by some locals.
It's a step in the right direction 
and this does exactly what for me? Not that I'm asking for anything either. I really don't care when liberal whites do the apology on behalf of their ancestors for slavery. Now if they apologize for the relatives behavior for the past several decades
Point being Ghana's people and government apologizing is pretty much pointless to me. I don't want anything from. Nice gesture but completely unnecessary and without practical or material value which again regarding the latter it would never cross my mind to ask for.
. Since they have no land and they have all the money, it's only proper they pay with money.
