Welcome to Gaia! ::

blaugh That's Easy; In my opinion, people will sometimes not want to go out of their way because they are afraid to stand out.

Me, I'm afraid of getting haggled for money by a hobo if I'm walking alone and I come up all friendly.

I use to think like you once "I wish I could help out the guy".... until he walked into a store the other day while I was around. the money the random hobo had just randomly collected; he literally passed al the possible edible sections and headed straight for the back where all the "drinks" were located. I purposely waited to see what he got, to prove a point to the cashier who also felt sorry for him.

The guy was carrying a can of beer. Talk about a dissilutioning sight.....

I have compassion, but after seeing that; hobos are just another form of strangers to me.

Without negative emotion, there would be less to avoid... Nothing, if taken far enough. Without fear of death, the human race certainly wouldn't have made it this far and if it disappeared tomorrow then so too would most of the human population.
Our whole world is built upon currency. Money is the most common form. It is the universal incentivizer. There are plenty of people who say that they don't need money to be happy. These are people who have never experienced true, grinding poverty. Money is no guarantee of happiness but poverty is a promise of misery.
Besides all of that, I find that sadness, if deep, dark, and black and pure enough possesses an intense and dire beauty. If you are plunged into the deepest abyss of misery that you can imagine and cloak yourself in a protective layer of hate then you can enjoy a beauty that you can find no where else... But only if you're deep enough to appreciate it. I've yet to find no one else in the planet that can see any beauty in their own personal unhappiness, but few people ever really did share my dark sensibilities.
