We could not make the angels happy
"My people have committed two sins: They have forsaken Me, the spring of living water — and have dug their own cisterns, broken cisterns that cannot hold water!" Jeremiah 2:13
The human soul cannot be satisfied with any of earth's good things. This is not the fault of the things of earth — they are good and beautiful, in their own way and in their own place. But the soul is spiritual and immortal. Money and fame and power — can never be food for a soul made in the Divine image; nothing less than God Himself can answer its cravings.
We could not make the angels happy by giving them gold and diamonds, and building them fine marble palaces to live in, and putting crowns and fine clothes on them. No more can we satisfy our own souls with such things. Men try to do so — but their thirst is only momentarily quenched — and soon they must drink again. Gratification only intensifies desire.
"Whoever drinks of this water will thirst again — but whoever drinks of the water that I shall give him will never thirst. But the water that I shall give him will become in him a fountain of water springing up into everlasting life!" John 4:13-14
