unfortunately integrity and business success are often negatively correlated (asserted without proof...)
While I agree that there may be some short term gains to be made without integrity, there are a number of examples of successful companies that work very hard to maintain it that have seen great success, whether it is the customer service ethic at an Amazon or Zappos, or the need for the late Mr. Jobs to make sure even the unseen components were of the highest quality. Companies with integrity tend to build more stab…
What you're describing is not integrity (or perhaps integrity limited to business-customer interactions only). The more challenging part of integrity is how you treat your business partners, workers (paying peanuts to workers who manufacture the iStuff while sitting on billions), if you dodge taxes etc. That's the money part as well - being greedy and heartless vastly increases your chance of making it big.
