A parable conceals a core message while other details are decorative. That is, these details may not have any true implication to the metaphor.
In the parable of the Rich Man and Lazarus, the core message is found in the last few verses;
29 “Abraham replied, ‘They (the brothers of the Rich Man) have Moses and the Prophets; let them listen to them.’
30 “‘No, father Abraham,’ he said, ‘but if someone from the dead goes to them, they will repent.’
31 “He said to him, ‘If they do not listen to Moses and the Prophets, they will not be convinced even if someone rises from the dead.’”
Who are the Rich Man? Earlier in Luke 16:14, it is written "The Pharisees, who loved money". So in the parable, a dead Pharisee is asking the Lord (Abraham) to sent Lazarus (vv24) rise from his dead to warn his brothers (other Pharisees), and Jesus told the Pharisees if they did not listen to Moses and the Prophets, they will not be convinced even if someone rises from the dead (vv31)
In all of Jesus' parables, this one stands out with a specific name: Lazarus. In John 11:1-44, the actual Lazarus was resurrected. Would it possibly be a solid hint to the Pharisees, potentially able to save some of them who understood the parable and repented?
As usual parables are rarely explained as well as the consequence it brought forth. But I don't think "suffering deserves paradise, and being rich deserves hades", for it does not harmonize with Christian faith. Jesus told the Pharisees they should listen to Moses and the Prophets, the same now Christian should listen to Jesus and the Spirit, otherwise, we will not be convinced even if a miracle appears in our eyes.
