pirate penguin, i am not convinced that a lot + often = only 100%.
That aside, i might point out that the components of success are supposed to be being good at whatever your business is. if your business is manufacturing then you have to be good at getting cheap raw materials, good at hiring the minimum of staff, good at paying the lowest wages possible, but good at keeping both your workforce and customer base satisfied enough that they don't cause you any problems (laqsuits, strikes etc), good at making components that are as functional as possible and don't break down, and good at getting your orders shipped on time, end result, you want to satisfy your customers so that your name becomes known as "good" (reliable, value for money etc).
Most of the above things break down once a company becomes a monopoly. for instance if you are successful at getting low cost raw materials then you will drive your competitors out of business and become a monopoly. then all of a sudden it is good business (for you) to make things that break, because everybody buys from you and so when their stuff breaks, they have to come to you to replace or fix it. you no longer have to worry too much about quality, or the welfare of your staff for the same (or similar) reason. once you actually are a monopoly, you can also start to make demands on your suppliers and those you supply. want to delay the european release of your product for five months? why not? nobody else is making them! in fact you could get your PR department to hype the eventual release and sell more units! similarly if you are the only buyer from your suppliers, then they have to meet your terms or go bust themselves!
this is why modern capitalism is a bad economic model. because it tends towards monopolies. and by the time a company has become a monopoly there's nobody who can touch them because they already have more money than everybody else (and sadly the "justice" system is run by money in our modern capitalistic system). a successful company are above the law or justice, and who's to say that's not why they became successful in the first place?
