Are We Moving Away From Slavery?

There is lots of literary evidence and depictions in art of crutches, walking sticks, staffs. We've got corrective foot worth for congenital conditions such as clubfoot. Shoes have been excavated from the Roman fort of Vindalander on Hadrian's Wall that show evidence of gay correction. And we even have accessible architecture. So, are we moving away from slavery? Because actually, it would be good to use a man's alphabet. You might as well use it right on as well.
