ELI5: Why does Walmart get such a bad rep when the other big box retail stores like Target and Kmart don't get the same hate?
gpt
Walmart has a history of treating their employees far worse than most other big box stores. They're also well known to use ethically questionable tactics (the common example is coming into a new town, setting their prices so low that they're selling at a loss just to drive their competition out of business, then raising rates up higher than they would've been had they just competed with the other stores). 

They're also the US's largest employer, which means all those company policies and shady practices are very well known to a large number of people, meaning more people are likely to be upset by them.
