The answer to the blank space is a term called relative deprivation.
Relative deprivation is a principle where individuals and groups lack resources to access the lifestyle and amenities that they are accustomed to or are approved by a society. It differs from absolute deprivation since the latter has a fixed definition as to what these individuals lack compared to most population on earth, not just the dominant group in a region.
These two concepts are commonly associated with the principles of relative and absolute poverty – where the former will always occur as long as social inequalities remain the standard of living.
