By getting stuff from China at a cheap price and then selling it to US consumers at a cheap price and taking the difference as its profit, Wal-Mart has an unbeatable system to consistently both defeat its competitors and generate a stable profit for itself long into the future. Other companies have started to replicate Wal-Mart but by now Wal-Mart has the additional competitive advantage of size which allows it to source products from China even more cheaply and beat out competitors in the US for store locations, distribution deals, etc.
Wal-Mart has an unbeatable system to consistently both defeat its competitors and generate a stable profit for itself long into the future Might be true, if they were the only ones doing it. Which THAT underscores the issue.
BTW most products in Wal Mart are not "Wal Mart" stuff. They are brand names who market their products inside of Wal Mart.
Those sub contractors of Wal Mart are the ones buying from China.
There are middle men in there...
Size does matter though. Thats true. Who wouldn't give a good price if you are promised $10 million in sales?
Just so you know though, if something cheaper comes along (potential free trade agreements or something) then China might not be the best or cheapest anymore...
Now I am going to sleep.
