I am not sure I understand your point...are you saying rich people can't be saved or that being rich is somehow a sin?
What the bible is saying is that Jesus was a socialist.
As to the rich being saved:
Abraham was rich, Job was the richest man in the East, King David was rich, King Solomon was the richest king on earth, etc, etc, etc.
So the rich can be saved, for the rest of the passage reads:
23Then Jesus said to his disciples, "I tell you the truth, it is hard for a rich man to enter the kingdom of heaven. 24Again I tell you, 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."
25When the disciples heard this, they were greatly astonished and asked, "
Who then can be saved?"
26Jesus looked at them and said, "With man this is impossible, but
with God all things are possible."
... so then, it is possible for the rich to saved!
