(Being able to buy ownership of a business, via stock or other means, is why wealth is concentrating in the first place.)
But you start getting into monopsony then. The people that you sell to are hyper rich and may pay a fair price, but there are a lot less people overall and their tastes aren't distributed like the general population. It's not the same market at all.
You sir, are a genius. I love that wording. That should have been on the welcome brochure we all get as babies, assuming we could read it.
As one dies, so dies the other—they all have the same breath. Man has no advantage over the animals, since everything is futile. All go to one place: All come from dust, and all return to dust.
Actually, it isn't. The book of Ecclesiastes, which you quoted, goes very much against the grain of the rest of the Bible, which generally tends more towards the idea that man is distinct from the animals, and does have a higher purpose, which is to serve God. Ask any Bible-thumping evangelical and they will be very quick to tell you that all do not go to one place, because their whole raison d'etre is to persuade you that if you don't follow exactly whatever particular flavour of Christianity they are pushing, then you will end up going to a very bad place indeed whereas they, of course are already assured of their entry into a not-so-bad place for all eternity. They will also tell you that the Bible never contradicts itself. I leave you to draw your own conclusions.
I just bought my first house which is about half that size and even then it feels too big at times. But it's a house I can afford. Being mortgage free by 39 means I get the flexibility to decide what the next act of my life will be about (spoiler: my kids). All it cost me was, I guess, a pool, a hot tub, an extra car, etc.
And all those empty rooms in the photographs! I don't imagine they see many days of being filled with smiling, laughing guests. Which is really the only true use of a house that big... you need to entertain, you need hundreds of friends to share it with, right? Otherwise what's the use? Maybe that's just me. I would probably get supremely depressed otherwise, all that space around me, waiting to be used, reminding me how empty it is.
Everybody gets old. Everybody dies. Everybody follows each other in a grand parade to oblivion. These people won the game the mid-20th century told them was being played, but everybody ultimately loses the Big Game.
