Alice Rosenbaum was born at St. Petersburg, Russia, in 1905 when Russia had its first Revolution.
After USSR was established, Rosenbaum was engaged in various anti-regime activities.
At that time USSR tended to expel potential troublemakers, so it expelled her who ended up in USA and took the moniker of Ayn Rand.
This is not a place to discuss her philosophies, but in one of her books there was a character whose family obligation was that the person had to double the family's wealth in his generation, and every generation had to double the previous gen's worth.
Rand didn't like children and few children ever appear on her books, but eventually, because the earth is finite, the wealth-doubling scheme would have hit a limit at some point and all the wealth in the world would not have been enough to double that family's wealth, like the fable of the chessboard (a guy , as a reward for inventing chess, wanted a grain of wheat at square 1, 2 grains at square 2, 4 grains at square 3, etc- by the time we get to the final, 64th square it would have taken about 1,600 times the yearly wheat production of the earth to fulfill the obligation. There are variations about how that story ended; in one version the inventor of chess was simply beheaded for offering a ridiculous proposition, and in another version, he transformed into the god Krishna, who still demands grains at his temple since the debt to him has not been paid off yet.)

Except people like Psy or a certain 1,343 years old, most Kpop acts have a pressure to outdo their previous promotion.
KPop is a cutthroat field where there are no permanent friends, and if an act is seen lagging, it is quickly overaken by another act which will be very happy to take over that act's position.
Even BTS cannot stay still. It has to prove itself all the time, which is why avoiding the military gap is quite important since by the time the military services are over other acts would have taken its places.
Newer acts have to outdo one another, plus their previous records. Companies have very short patience and acts which can't outdo their previous promotions are not easily given another chance.
When the Big Three , SM, JYP and YG, dominated KPop the acts at least had some security since their companies would protect them and their positions were secure.
But there is no security at all, and every act has to outdo everyone else.
I do think that at some point that will hit a wall, and a collapse might occur, but for the time being the KPop acts can't sit still.
This chariot race, where there is no rest, no respite and constant pressure to advance, has transformed the post-Covid KPop scene a lot.
People like Psy and a 1,343 years old will retain their positions since they are established and their positions are secure. However, KPop acts are like employees, and even the most successful acts are subject to their companies who want them to do more. So there won't be any respites for the various KPop acts, big or small, in today's world.
