The above quotation comes from the hand of Karl Marx, and is somehow still seriously proselytized to various people around the world, as well as being argued as a legitimate alternative to capitalistic or other economic systems, as something that would be far better for society in whole. Look, there actually isn’t anything wrong with Marx’s belief, for it seems to make eminent sense, while also seeming to be quite fair and considerate, but the crux of the problem with this belief, though, is that the only dimension that this could ever conceivably come to fruition, is never going to be this earthly plane, but instead it would have to be Heaven. In other words, Heaven probably is a place in which those with great ability get great things done on behalf of that Heavenly realm without desiring anything more in return, and those who have great needs are provided with Heavenly assistance to fulfill those needs.
Regrettably though, this type of philosophy will not ever work in this material world, because human nature is human nature, and while there are a meaningful amount of people, that are empathetic, sacrificial, good hearted, generous, caring, patient, as well as having other wonderful qualities, they are clearly outnumbered by those that aren’t necessarily bad, but rather have an innate desire to get from their life, something more than just their basic needs fulfilled, for they desire to have something more to aspire for and to have as their own. That is to say, many a person desires more than what they need to actually just live on, for they want to have the satisfaction of getting that which they believe will bring them more happiness and contentment, regardless of their ability or their legitimacy in meriting such.
It needs to be recognized that we are each individuals, actuated by beliefs and desires that are unique to our own selves, of which, because we are all different, our priorities and desires are going to be different, as well. So that, some people are motivated by desiring to be acclaimed by the members of their community and beyond; whereas, others are motivated to selflessly do right to others, because by doing so, they feel better about their selves, and so on. Basically, we are not all cookie-cutter people, but rather each of us has our own abilities, our own needs, our own desires, and our own goals. So then, for a certainty, there will be conflict one with the other because of this, which isn’t necessarily bad, if each person, thereupon, gives a little to get a little.
To believe that there ever could be a well-functioning society in which every member believes that it is all for one, and one for all, is a healthy philosophy to have, but the reality of the situation is that because we have different priorities and different outlooks, this will not ever occur. That said, societies can be far better than they are, if more of us did our fair part to help make society a better place for our good participation in it, by using our individual ability and knowhow to accomplish such, and thereupon helping to fulfill the needs of others who are needful of society’s help.
