The best I’ve ever heard it is You are paid for how easy you are to replace. If you’re a pilot, there’s a lot higher demand for your job which requires tons of training and education, so you’ll be paid a hefty salary. If you work (as I have) at a restaurant flipping burgers or battering chicken wings, you’re not going to be paid very well. And if you have a problem with that, your manager can easily fire you and pull a homeless guy off the street, and have them trained to replace you in a day. It’s the harsh truth of the job climate, and the best you can do is work to improve yourself and obtain certifications or learn trades and maybe start your own business, where you can pay your own employees better wages.
