Here's my guess :
WalMart and MicroSoft both avoid paying benefits to many of their workers by hiring either for a temporary period or paying by contracted services.
Most of WalMart product is made outside the USA. Many of MicroSoft's engineer's are temporarily employed and are from outside the USA . This is all a generalisation, but shows a shrewdness of the corporations practices. They are both globalized in their business model and the profits are still unimaginable yet to come!
I've stopped going to WalMart and I own a Mac computer, no more crashing and security issues

Adage: 2 things are certain in life; Death & Taxes. Therefore; God & Beelzebub had a meeting to fix the problem. A mighty storm prevailed for ages until finally they ended the storm with the agreement: From now on Anyone whom chooses doesn't have to die. "Everyone wins said Beelzebub. You get an eternally grateful bunch of worshippers praying forever for lower taxes as I goad & prod them forever with higher & higher taxation."
