Final answer:
Critics of the cultural skyscraper model do not usually express concern about the accessibility of low culture, as it is typically readily accessible and widely relatable. Instead, criticisms often focus on class stratification and the model's potential to overlook the broader cultural context and to devalue popular cultural forms.
Step-by-step explanation:
What is not a concern critics using the cultural skyscraper model have about low culture? Critics of the cultural skyscraper model, which distinguishes between high culture and low culture, often point out various issues. However, one aspect that is not commonly criticized is the accessibility of low culture. Critics do not usually express concern over low culture's availability to the general public, as low culture is typically easily accessible and relatable. In fact, popular culture and low culture are often interchangeable terms in this context, representing the widespread and mainstream patterns of cultural experiences within society.
On the contrary, criticism of the cultural skyscraper model tends to focus on how the model may contribute to class stratification, potentially reinforcing stereotypes based on economic class. Other concerns might include the model's lack of attention to cultural context and the potential devaluation of popular cultural forms when compared to the so-called higher culture, which is often associated with the elite sectors of society and characterized by more formal and exclusive events.
