In technology, sure. In somewhat less easy to define things, not so much. Rich people tend to have better education, better health care, less worries and stress (or at least less existential worries and better coping mechanisms), and better "life opportunities" as far as anything that requires money is concerned. Poor people can't work in industries where unpaid internships are commonplace for example, because they need to earn money for rent and food. Rich people can work for free if they choose to.

Whether a vastly extended lifespan falls under just technology, and thus ends up as something everyone can have, or something else that is actually limited to the rich is something we don't yet know.

For example, if the key to a longer life is technology plus retiring as early as possible to limit stress, poor people aren't going to live longer.
