If escalator mechanics are not very important people then how is there a crisis when they are missing? Do I declare a labor crisis because I can't find senior developers to work on my website for $10 per hour? The buyer doesn't get to decide that a job is not important so someone else is expected to do it cheaply. Either the job is not important so its no problem if no one takes it or it is important so you will pay whatever it takes to get it done.
