> Prosperity is not a zero-sum game But in many cases it's close to it. A company that reduces its expenses by 5% will eventually bankrupt its competitor that wasn't able to do so (all else being equal). A 5% contribution to efficiency allows it to take over 100% of another company's market. The success of a company is in a very large part determined by its competition - more competition means starting a new company is harder.
