There is absolutely strength in numbers. That is why we form groups and societies. Think how strong we could be if the entire population of this planet could stop fighting each other and instead support each other? I doubt I will live to see that day, but boy would that be something!
Steemit was designed with that idea in mind, however we still have too many people that cannot see the benefit of working together to help each other and are instead attempting to help themselves. @papa-pepper is a great example of how helping others actually brings success to yourself. The proof is right here. I don't know why some people just can't see it.
