That is a very nice thought, and the world would be a nicer place if everyone acted this way
However, back to reality
Your sentiment and a bus token will get you downtown, but not much further.
Your competition in business does not act in accordance with your "people helping people" principle.
Its a dog-eat-dog world and you do not want to be wearing milk bone underwear.
Actually, in reality, there would be no road to carry me without people helping people. As a society we have decided to help each other, pool resources, and make the world better together. We pay taxes to make the roads we all use. I'd rather we didn't put so much into the roads, actually... and had a lot less cars, etc, but I give that up because it is pointless to argue with the consensus of modern society. As a collective we have built a system that helps us all, though it continues to evolve and will change over time. If everyone decided to just eat anyone who got in their way, we really would all still be animals... and we would still co-operate even then.
I know that we are all sure that nature is dog eat dog, survival of the fittest... but that isn't the whole story either. Creatures live in niches to avoid competition, and do well at it. And long before there were dogs to eat dogs, there were single cell creatures who got together and formed the first multicell life forms, that is, cells co-operated with other cells, began to specialize, and eventually we end up here.
And somehow, I have no business competition. I work in the education racket. That is all about building a society in co-operation. Of course one can disagree about how things are organized, but that argument is contingent on a safe place to have the discussion, a civilized world built through the work of other people, throughout history, for the common good.
Civilization evolves - at one time basic necessities of life were scarce, and someone who couldn't walk, or was 30 years old, was a drag on survival of their fellows. They either were left out in the cold, or went there themselves to help their fellows keep going. Now, just because you can't walk doesn't mean you have to die to save the rest of us... and people in wheelchairs have done great things for us - who is that smartest guy in the world who can't even talk without a machine to help him? And we don't all need to contribute to that level - a good friend in a wheelchair can make life better for anyone who is lucky enough to know them.
