Higher education always improves the quality of life. Quality of life, in a much broader concept, has something to do with your knowledge. For example, the more knowledgeable you get, the happier and less stressed your lives can get. You then know what life really is, and what exactly you need to have to enjoy a blessed life. If someone does well in his job, maintains a good social life and balances all these with a happy personal/family life, then it can most probably be considered a well-balanced life and all that all can come with a good education.
