I think most people are listening to the money because that is what they've been taught. Most probably don't know what currency really is, how it works, and that we're all (most are) modern slaves because of it .
If we all knew the truth about currency, it wouldnt matter how much money you have and that homeless man might be heard because of what he's saying, not by his wallet.
I completely agree, in the modern world we are salves to money as the power of money is enforced upon us throughout the time we spend in formal education.
