Star Trek: The Next Generation1987

Dr. Timicin:
Fifteen to twenty centuries ago, we had no Resolution. We had no such concern for our elders. As people aged, they... their health failed. They became invalids. And those whose families could no longer care for them were put away, into... deathwatch facilities, where they waited in loneliness for the end to come, sometimes... for years. They had meant something; and they were forced to live beyond that, into a time of meaning nothing. Of knowing that they could now only be the beneficiaries of younger people's patience. We are no longer that cruel, Lwaxana.

Lwaxana Troi:
No, no, you're not cruel to them, you just kill them.
