Salvation does not merely mean going to heaven after our physical death. Salvation in Jesus means recovering wholeness right now in new resurrected life. It means through the spirit becoming everything that Jesus is in relationships dedicated to humility, reconciliation and love.
When Jesus said "Blessed are the poor (or poor of heart)" he was not praising poverty as such. Quite the contrary: he was warning us that the kingdom of God (or of heaven on earth) would never be realized, much less possessed, by the avaricious or the greedy.
