Unquestionably, it is true to say that most people consider that a university degree is the only way to get a good job. I think this is true in certain areas, while in other areas, a degree is not as useful.
To begin with, many people have a dream to become a qualified professional, and there is no doubt that becoming a doctor or lawyer, for instance, is only possible with a degree. Another advantage of graduating from university is that it provides more options when choosing a job. Most employers will be more impressed by a candidate who has a university degree than by a candidate who has only school qualifications because it denotes a certain level of intelligence and education.
On the contrary, there might be some benefit to starting your career early, especially if your chosen field is one which does not typically require a university education. This would apply to somebody who wants to be a watch mechanic, or a fashion designer, or a lorry driver, for instance, who would not think going to university is essential. The hands-on experience you gain in your job while others are studying for a degree can give you a distinct advantage. I once read about a man who left school at sixteen and went on to become a wealthy and successful investment broker. He claimed that he had learned all he needed to know by working in his chosen field and that he could not have done any better by getting a degree.
So, to conclude, it is possible to get a good job without going to university. But pursuing some professions, such as lawyer, engineer, professor, researcher, and so on, requires a degree, and, as stated above, a university degree could potentially open more doors to more options and highly regarded and well-paid jobs.
