Is it wrong to give homeless people marketing advice?

It’s something I wondered while heading to Brooklyn last night. A middle-aged gent, homeless and needy, he explained, boarded the downtown A and started his spiel. He didn’t need food, he said. He didn’t need shelter, what he needed was cash for clothes, as he only owned two sets, the others were back at the men’s refuge. Had he have stopped there I feel he would have been successful in his quest for donations however, he continued on revealing the following details:
* He had just got out of jail and was on parole
* He had been deemed mentally unstable with a combination of schizophrenia and bi-polar
* He was a former drug dealer who had no desire to go back to jail
* He couldn’t get mental health benefits as had been told by his psychiatrist
* He was waiting to lodge an appeal, which could take up to six months
* Ect. Ect. Ect.

This is where I started to wonder whether I should interject, he was loosing the crowd; people had left the train, others had boarded. He needed to keep his pitch sharp and concise. Say it in less than 30 secs, I wanted to scream. Grab em by the balls, pull them by the heart strings. Let’s get together and work on it, come on you can do this, I silently chanted. I didn’t however, which brought me to this rather odd question, could a positive program called marketing 101 specifically for the homeless be introduced by some sort of government agency? Mm, food for thought.
