What Walmart represented was really just a kind of acceleration of the cancerous growth and metastasis throughout the body of the economy, spreading to the bloodstream. The likes of Amazon only made things that much worse, a far more aggressive and parasitic malignant cancer, or maybe even HIV of humanity that spread even faster and harder, and was able to even overcome foreign immune systems that had previously been able to hold the Walmart cancer at bay.
I fully understand why people would see Walmart coming to a town that was likely also suffering as an early indicator and outlier to the de-industrialization /globalization that wouldn’t impact more consequential lower-middle class until a bit later and would largely be experienced as benefits by the upper middle class that you also likely occupy now and for a while now.
For context, this same process seems to be unfolding at an even more rapid pace in Germany right now as the industrial small business base is being massacred and that will have the same kind of devastating effects on the dependent small, family owned businesses and retail companies that have been a moat to the likes of Walmart, Amazon, and even by extension, the Ubers and Food delivery services and digital services that serve a deracinated and shattered population in the USA currently.
