Let's discount that programmers are human begins: let's assume programmers are exactly like rotary tools that can run 12 hours a day, everyday, including weekends. Every tool has a fixed number of cycles before something gives and repairs need to be made (or the tool written off and a replacement obtained). Depending on the price and availability of a tool, some businesses make conscious decisions to limit the number of hours they use a tool, so as to extend the life of the tool. Now if we are to consider that we are the said tools, and once we wear out, the onus is on us to repair ourselves and bear all costs of doing so (because the business "writes us off"), we might have more clarity into pricing ourselves? If we want to add to that, that we are actually human beings, some more clarity perhaps could be obtained. I invite your opinions and feedback.
