Every time that philosophy has been implemented it has resulted in mass death and social collapse. Meanwhile when “useless” people are given tools and resources some of them wind up less useless.

Isaac Newton was probably autistic with bad enough social skills he was generally despised. Stephen Hawking had ALS. There are cultures who would have declared both of them useless and unfit for life. Hell Hellen Keller was an author and important political activist (cofounder of the ACLU) despite being deaf blind, because people gave her a chance and worked with her to learn a form of communication that worked for her.
