Having grown up in MI all I ever knew was Meijer, the first Wal-Mart didn't appear until after I had already moved away. I moved to the South, which is of course where Wal-Mart is King. Honestly I never really gave Meijer a second thought until after having moved away and realizing how good Meijer's really is after having to have to shop at Wally World.
Wal-Mart sucks plain and simple. The stores are nasty, the workers are horrible and if your lucky they speak English, the areas where they open seem to go downhill after Wally World opens there, they cater to illegals...I could go on. Like somebody else here mentioned, their chi-com merchandise is garbage, I have no idea if Meijer's uses third-world child labor to the extent Wal-Mart does, but either way, I have noticed a big difference in the quality of the merchandise. Even before we stopped shopping at Wally World, I quit buying any non-food related items because it just seemed like one after another clothing, toys, houseware, etc. it was all junk, in the trash after a few days-few weeks. Even somewhat known brands it almost seemed like it would be worse if it was from Wal-Mart.
Before you jump on the 'it's capitalism the free market will decide' bandwagon realize what Wal-Mart will do to an area. Then after it's too late and your stuck w/ONLY them, then you will really rethink the 'it's capitalism...' crap.
