Pawclaws,
My guess is that JC Penney, Mr. sears and Mr. Roebuck, Mr. Walton, et. al, all started their stores because they saw a need. (Didn't JCPenney start in Kemmer wyoming??)
I think what you see in common with the companies you mentioned is their commitment to "Pay among the leaders" and have a good environment. Part of being able to pay well is being able to make lots of money. And being able to re-invest in R&D and into sales, etc.. etc.. But, don't be fooled for a second, that the purpose of Apple is to make their employees rich. The goal of Jobs and Company is to Maximize the Long Term Sustainable Wealth of the Company's shareholders. Anything else is a breach of Fiduciary Duty. One of their tools is to keep good employees, and to do that, they "pay among the leaders", and have parties every so often.
We don't have to look back to far in Apple's history to see the lean times, and they weren't the "happiest of campers"...
