There's also elasticity of prices. There's a limit of how much people would pay for a job. I.e. if you have a washing machine repair technician, you can't charge as much as a new washing machine costs for repair, because then people would just go and buy a new one instead. There's some point for many jobs where it's better to not do the job or find some alternative way of achieving the same. Of course, if your roof is collapsing, you don't have a choice, but in many cases you do. So you would either not do it, or postpone it as long as you can - thus reducing the income of the job supplier.
