Short term, for 70-80 years, while in this fleshly body, from a creature-comfort standpoint: The Materially Rich
Long term, for eternity, outside this fleshly body, from the standpoint of absolute fulfillment and love: The Materially poor who are Spiritually rich.
Luke 18:18-30 (New International Version) - The Rich Ruler:
18A certain ruler asked him, "Good teacher, what must I do to inherit eternal life?"
19"Why do you call me good?" Jesus answered. "No one is good—except God alone. 20You know the commandments: 'Do not commit adultery, do not murder, do not steal, do not give false testimony, honor your father and mother.'[a]"
21"All these I have kept since I was a boy," he said.
22When Jesus heard this, he said to him, "You still lack one thing. Sell everything you have and give to the poor, and you will have treasure in heaven. Then come, follow me."
23When he heard this, he became very sad, because he was a man of great wealth. 24Jesus looked at him and said, "How hard it is for the rich to enter the kingdom of God! 25Indeed, it is easier for a camel to go through the eye of a needle than for a rich man to enter the kingdom of God."
26Those who heard this asked, "Who then can be saved?"
27Jesus replied, "What is impossible with men is possible with God."
28Peter said to him, "We have left all we had to follow you!"
29"I tell you the truth," Jesus said to them, "no one who has left home or wife or brothers or parents or children for the sake of the kingdom of God 30will fail to receive many times as much in this age and, in the age to come, eternal life."
"No one can serve two masters; for either he will hate the one and love the other, or he will be devoted to one and despise the other You cannot serve God and wealth."
