The original post was "Can you explain how exactly?" You misread the comment. The only confrontational word in that question was "exactly." It's a fair question because of many people who do remember the pre-Walmart times (their big expansion was in the late 90s-early 2000s). The going narrative at the time was that local businesses were destroyed and this was a tragedy. Additionally, Walmart was one of the first retailers to primarily buy products from Chinese manufacturers instead of sourcing American-made products (after the death of Sam Walton). There were frequent news stories about how a factory closed and all the laid-off workers got jobs at minimum wage at Walmart, selling the very goods they previously made. Several municipalities enacted "no-Walmart" legislation and zoning regulations. Even South Park made an episode about the phenomenon. Looking back, it might have been unfair to demonize Walmart for what was likely the rational decision to make in a competitive environment. But taken in context for the times, Walmart's growth in the late 1990s/early 2000s was controversial and frequently challenged.
