Final answer:
Identifying the sole city in the United States without a Wal-Mart is difficult as the company is widespread, and new stores can open or close. However, the impact of Wal-Mart, known as 'Wal-Martization,' reflects concerns about their business practices impacting local businesses and employees.
Step-by-step explanation:
When discussing Wal-Mart and its profound impact on local economies and retail landscapes, it is important to note its omnipresence almost everywhere in the United States. However, identifying a city in the United States without a Wal-Mart turns out to be quite challenging, as Wal-Mart has extensively penetrated both urban and rural markets. The assertions about Wal-Mart's effects on the economy, particularly the concept of Wal-Martization, reflect the concerns regarding low wages and the marginal benefits provided to employees.
Moreover, despite the presence of Wal-Mart in numerous locations, there may be instances where local businesses, like the general store in Natchitoches, LA, survive due to unique factors such as tourism appeal. Yet, pinpointing the 'only city' without a Wal-Mart is not straightforward information available to the public, as new stores may open or close, and information might be outdated or subject to change.
