That's a propaganda to make people become employee in their whole life because they keep thinking, if they lost this job, they won't get another one.
Most of the time, if you search other jobs when you still have your current job, you can't change your career. So let's say you're a welder, your top job would be an underwater welder. It's because you have no time to learn other skills and you're already tired.
Only brave people can earn much money, like people invest in something, they spend money to get money. People need to have their own "roadmap" instead of worrying to lose their main job.
I will be happy with any job that I can get because to me it's not just about the job but what I am going to use my earned money to do, many people seek for convenience in everything they do but that's not how life works, you have to give something to get something in return.
For job it's either you are happy with it or unhappy and the sacrifice is your knowledge or energy in exchange for money, that's the way of life, but something have to keep you going, and that for me is investing the money into something that can create an escape route for me so that I won't have to work again in the future.
This is the main reason why I am in this crypto space, to retire myself and not have to work all the days of my life, this gives me enough confidence and reason to keep grinding in the rain, for one day will come that the sun have to shine over my head.
