And this applies even across huge orders of magnitude differences, hundreds, thousands, even billions. To bring this back to HN relevancy, consider how to get on top of this problem at a corporate/startup level. Companies that solve those deep, omnipresent, indirect costs problems (often through development of high quality internal tooling) have a huge advantage over their competition, because doing so is a huge force multiplier.&lt;p&gt;At one point a coworker of mine raised the idea that when you do some process that is painful sometimes it means you need to do it more. Because doing it more frequently can force improvements in process, technique, or tooling which then produce dividends.</text><parent_chain><item><author>rayiner</author><text>Fun fact: the banning of leaded gasoline was one of the biggest regulatory successes in history, and went a long way to validate the model.&lt;p&gt;The use of leaded gasoline was a classic market failure.
