What makes you think that a person planning on living for 1000 years would go retire for 90% of their life? What makes you think that a person who lives from paycheck to paycheck would be able to afford anti-aging treatments which are likely to be (at least initially) very expensive. Lastly, I doubt that a centenarian (or multi-centenarian) would be stupid enough not to save a $100 in an index fund to come back a century or two later to find a sizable amount in-place waiting to be used? It is very likely that anybody over ~300 years will be filthy rich because they have had hundreds of years to build up interest on their investments and they have several hundred years of experience in what does and doesn't work in life, not to mention 300 years of contacts.
