That's kinda true, money is the boss because it's the one who control people. Even if we try to deny it, we can't change the fact that we're always seeking for money, needing a lot of money, and won't be able to live without money. Money can really changes people, from good to bad, or even from bad to good. We can't change anything though, the system is made, and we'll forever be in the hand and control of money.
Yeah, nowadays money means power, if we can buy car and food with shits lying on the street maybe people will consider those shits precious but no, the only way for us to accumulate power is through accumulating money, that's just how the game works.
back when humanity still exchanges goods to each other, i'm sure some commodity considered more precious than other so some people may hoard them, same thing with money, it's considered precious because it's the most versatile means of exchange, that's why people also hoarding it nowadays
but the ridiculous thing is, fiat that's considered money mostly made of paper, kinda strange lol.
