Big AG is a problem too they squeeze out the Mom & Pop operation in volume.
Initially just like Walmart but as they consilidate , buy up , or drive more outta buisness prices are lower but then they put the squeeze on ya..
Take Walmarts Grocery Section sure their cheaper for canned goods, packaged , that kinda stuff..
Fresh stuff and Dairy ya could actually do better at Piggly Wiggly or your "Local Supermarket"
But Walmart knows they already got ya there for the rest of it so youll pay more for Dairy , Produce, & Meat have ya thinking ya made a killing on rest of stuff..
To be "Fair" Butter & Eggs are better deal at Walmart but eh "Loss Leaders"
