That's correct. It wasn't wished away. Slavery and other forms of cheap labor were part of the human condition for millennia.

It took revolts, revolutions and changes in mores for things to advance to where they are today. Yes, some day, we may all enter a new world order where everything is placid. We're not there yet and thinking we can wish ourselves there in the near future, let's say, extremely optimistic, to the point if being wishful thinking.

Perhaps most importantly is that servitude and slavery became economically untenable.
