What societal structure is key in the world of GATTACA?

In the world of GATTACA, the societal structure is fundamentally built on a rigid hierarchy based on genetic superiority. This dystopian setting emphasizes the value of one's genetic pedigree, where individuals are often judged and categorized according to their DNA. People who are genetically engineered and considered "valid" enjoy privileges and opportunities that "invalids" or naturally conceived individuals are denied. This strict classification influences everything from employment prospects to social interactions, reinforcing the notion that one's worth is directly linked to their genetic makeup rather than their abilities or character. As a result, the film critiques the implications of a society that prioritizes genetic determinism over human diversity and personal identity, making the concept of genetic superiority central to the narrative's conflict and themes.
