When an era ends, many things cannot be bought with money. After the era of slavery ended, it became difficult to own slaves, as directly physically restricting and exploiting others is illegal and completely unacceptable in society. Even if you had your own island with the wealthiest and most powerful people in the world, the truth would eventually come out. After the era of servants ended, it became difficult to have maids; those in coffee shops cannot be considered maids. Regardless of whether equality actually exists, the mindset of most people has been cultivated from a young age to believe in equality for all. Now, even if there are servants, it is merely an employment relationship; money cannot buy the master-servant mentality, respect, or obedience, and one must overcome the physiological self-interested mindset. This is something that must be cultivated from a young age; money can only buy superficial compliance. Similarly, when the era of hired help ends, it is likely that no matter how rich you are, you can only use more realistic robots. Because when the era of robots becomes widespread in every household, it will also mean a new liberation of productivity, and the pre-AI fiat financial system based on human division of labor and wages will collapse. In simple terms, money will become useless, and no one will care about you.
