Money gives you power.
Power can be used to achieve more power.
Were this not so, of what use is power?
Doesn't the richest player in monopoly dominate the board, eventually driving the other players to ruin?
Such is the tendency of unchecked wealth in real life.
A thousand and more years ago, land was wealth.
The more land someone acquired, the more power they had, and the more land they could take from the less powerful.
Unchecked, except by the few equally as powerful, the noble class and feudalism evolved.
If people today were allowed free reign to use their wealth to accumulate more wealth, we would have a return to feudalism, except that today's wealth is not symbolized by crenelated walls--so if you identify feudalism with castles, vast domains, and chain mail, you might miss the modern variety.
