Pretty much every culture ever has considered people who are unable to contribute to the functioning of society to be dead weight (thus why being disabled had been a curse unless you happened to be born into wealth and why female infanticide was so common in much of the world). Being old didn't tend to be as much of an issue in the past as people regularly living past the typical retirement age of ~60 is a fairly recent phenomenon. Modern societies (especially the so called "ponzi scheme capitalist culture" ones) tend to go far beyond pretty much all past societies to support such people.
