I agree with the above posts but do think equipment has and will continue to move into the leather industry as the bigger manufacturers continue to try and minimize costs. However most people on this forum are small shops or hobbyist and either do this because they love the feeling of making something by hand or because they have found a niche that they can fill no one else has. As mentioned above you need to go to a small leather shop and see how unfeasable the expense would be to them. I think that if there was a cheaper way to create a finished product some would use it after all there are some on this forum that use sewing machines, computers, copiers, etc... But to be stamped hand crafted it still has to have hands on it. On a question to you, if you had a choice would rather have a hand made belt, wallet, shoes,etc.... As compared to a imitation leather one made in china from Wally World? Why or why not?
Good luck on your dissertation, hope this helps
