Some conflict theorists ascribe to the idea that as time and technology move forward, elderly people are left behind and they lose social standing and power. Which specific theory does this describe?

Social constructivism

Explanation:

In the framework of the theory of social constructivism, ageism appears as a mechanism for imposing the construct of old age - any attitudes, actions, or institutions that subordinate people on the basis of age or otherwise, attribute to a person various social roles based on his age. The consideration of geriatric problems within the framework of the theory of social constructivism allows contrasting the medicalist approach with the concept of positive aging, one of the elements of which is the reflection of negative gerontostereotypes by older people and their overcoming in their own lives.
