Posts like yours sort of amuse me. Fifty patients a day? Hardly. It might happen on a regular basis of sorts, but hardly fifty a day and hardly all incapable of fending for themselves like this paraplegic.
Yes, Jesus told the disciples, "The poor will always be with us," but the context was that He was still with them in physical form and there would plenty of time after He went back to heaven for them to care for the poor. That is now.
You ask a lot of questions about the guy that none of us have answers to, including you. He may or may not be like the guy you know who would rather read books than read. None of us know that. We do know that he was dumped onto the streets directly from the hospital with a hospital gown and a colostomy bag and without any ability to move from the waste down. There's NO excuse for that. Absolutely none.
And, in response to your second quote from Jesus, again one that you have taken out of context, Jesus told the man to pick up his mat and walk AFTER he had healed him. Did ya get that? AFTER he had given the man the tools he needed to be ABLE to pick up his mat and walk, not before. There's a lesson in that for us as well.
"He may or may not be like the guy you know who would rather read books than read work."
"...and without any ability to move from the waste waist down."
