Final answer:
The statement about young artists in the seventies in New York is false; post-war economic and social changes, along with new artistic movements, allowed artists to redefine art and access alternative venues beyond market driven constraints. The statement is false.
Step-by-step explanation:
The statement that young artists working in New York at the end of the seventies could access alternative spaces and other established institutions because their art production had marketplace value is false.
The late seventies saw a change in the art world's dynamics, with various critiques and structural changes in the marketplace challenging the validity of contemporary art's market value. New styles and movements, such as Neo-Expressionism and conceptual art, prompted systematic reevaluation by artists and feminist theorists like Griselda Pollock.
Moreover, post-World War II, the societal influences of capitalism, the free market, and significant cultural shifts allowed artists to redefine art, diverging from traditional realism towards abstraction and expression of emotions. Artists like the Abstract Expressionists found community in lower Manhattan, fostering innovative artistic directions amid a shifting global art center. The transition from Europe to America and a post-war economy welcomed artists seeking to reflect a complex world, rather than produce works of art that squarely aligned with market values.
