I don't care who you are, how much money you have, The fact that you speak of a dollar as though its insignificant tells me you are ignorant.
Every dollar counts.
This argument is the same as when people say. "out of all america, My vote doesn't matter."
That view is nothing more than a mental weakness. The submission to a fallacy.
The fallacy is that the components of a system are not correlated to the function as a whole. In addition the logic behind the argument is not isolated, it is wide-spread.
Thus If everyone who believed their vote didn't matter voted, then the results of an election could very likely change.
All life, All items, All components function toward a point or purpose, that is independent of your understanding of that purpose.
The same is true of every dollar, even penny that makes up the system you call "wealth."
