In a society where people are afforded the freedom to attempt to choose their own career path, preoccupations, and quality of life, it is incumbent upon them to obtain, as they can, the wherewithal to do so. There are no guarantees of outcome, no guarantees of success. It may take many attempts for an individual to succeed, however they choose to define success.
The concept of a living wage is to my mind, anathema to an individual's success. We all possess talents and abilities in unique measure, and some will need to work much harder to achieve success than others will. Attempting to set an equality of outcome is foolish in my mind as it requires holding achievers back, not improving the output of underachievers. We don't need government or a helping hand from society for that - people just need to accept the responsibility for taking care of themselves. There's nothing selfish in that.
A person should be paid their worth, and that worth should be based on the value of the work they perform, as well as the quality of that work. In other words, the wage of a marketable skill. A person must be prepared to move to another city, sometimes frequently. They may have to change professions or go back to school. That's probably more true now than ever before, and I don't see anything wrong with that.
