I understand what OP means, for this issue: considering the example above of your story, that worker can accept for the sake of food and clothing or for the sake of family life or children that he chooses a job to earn money that he does not like or does not have the time and necessary conditions. Even in my country, university graduates cannot find a job in their major, and life forces them to choose another profession to earn a living. That is a forced choice. On the contrary, if that worker chooses a job that is not interesting but has a better salary than their favorite job, it means that the worker chooses and accepts their opportunity to earn money, basically going to work to earn money.
No matter we are doing what kind of work . The matters , how much we earn from our job or business. Government jobs are good and we enjoy on government job and of someone is doing work under an uneducated person and he is facing difficulties on job . He is on wrong route and he has to change his mindset if he wants freedom in life. OP is right because job is like a slavery and business owner treat us as he bought us for 8 hours. Of someone is doing business, he is on best route and he will be successful one day . You have to do the things what you don't want to do and you can't enjoy life with your life freely because owner disturb us when we are close to his business.
