Dear reader, if you bristled at how casually this statement ignored that compounding returns are a feature of the real world that we want our economy to model and encourage, now you understand how a normal person feels when a megacorp or megacorp cheerleader casually fails to account for everyone they displaced and stepped on in order to capture the value that they did. "Negligent accounting" is a strategy that points both ways.
