Oh please. The rich always pay for the research and advances that the poor eventually get for commodity prices. And even if we fully cure death by aging, death by accidents puts the average lifespan somewhere in the 1000 to 2000 year period, given the drastically dropping birth rates in the first world, we'll have more than enough time to reach space or colonize the oceans, or build low orbit cities. With every new 1000 people we get 10 new scientists, 10 new engineers, 10 new software guys; and technological advancement is easily sharable.
