While it would be nice to be hugely wealthy, the down to this is your utter detachment from reality.
The Bible puts it all into perspective:
Matthew 16:26-28 26 For what will it profit a man if he gains the whole world and forfeits his soul? Or what shall a man give in return for his soul? 27 For the Son of Man is going to come with his angels in the glory of his Father, and then he will repay each person according to what he has done. 28 Truly, I say to you, there are some standing here who will not taste death until they see the Son of Man coming in his kingdom.”
Mark 8:334-38
“If anyone would come after me, let him deny himself and take up his cross and follow me. 35 For whoever would save his life4 will lose it, but whoever loses his life for my sake and the gospel’s will save it. 36 For what does it profit a man to gain the whole world and forfeit his soul? 37 For what can a man give in return for his soul? 38 For whoever is ashamed of me and of my words in this adulterous and sinful generation, of him will the Son of Man also be ashamed when he comes in the glory of his Father with the holy angels.”
Luke 9:25 For what does it profit a man if he gains the whole world and loses or forfeits himself?
