Crushing mom and pop stores isn't the only issue Walmart and Amazon share. Both have mistreated employees and stole product designs to push their own versions of popular items undercutting the original. Walmart employees weren't peeing in bottles, but unsafe working conditions and union busting have been problems for both companies. Walmart.com is known for selling counterfeit goods, while the physical stores routinely sell dangerous items. It seems that filling your store shelves with the cheapest goods from the third world isn't always safe for your customers.

I do think that fixing a lot of the "quibbles" people have concerning Walmart and Amazon would help make things more competitive and help give smaller stores a better chance though.
