I'm not certain their reputation will change much so long as they can still ship a product to my house in one day for less money than at a physical store, and have effortless returns.
Does it actually? Or does it just have a hideous reputation among the upper classes because it is a thing of the lower classes (like country music and pickup trucks)?

But Walmart was often the only shopping center in a 40 mile radius for much of the US, meaning you had to shop there regardless of how you felt about them.
Walmart has a hideous reputation in certin area's normally upper-middle to upper class urbarn area's with high population density... This is also where they have very few, or no stores and the store they do have are not their "SuperCenters"
Outside of these area Walmart has a fine reputation and is generally well received by the population.
