Such abuse!
Good thing I love you all so much.
(of course, this means that I will find a wall somewhere on DOF to make Denise walk up!...and down again....!)
The donkey stuff we saw in Mexico was pure tourist bait. Bad for the animal? sure, I'm guessing that it was. Photo op for the tourist? sure, I'm guessing that it was.
I would suggest that you avoid it wherever & whenever you see such stuff.
As an animal lover, I really doubt that I could ever ride the donkeys up the 'hill', if they were as 'worn' as has been suggested here.
