"Internet access is now a necessity ?"
Exactly! You've just summed up the problem with the term "living wage". It's totally subjective and changes on an annual basis. I don't know what arbitrary wage these spoiled university brats would set as the minimum... but I guarantee you it would cause an unemployment rate of well over 15%
Living wage depends on the country and climate. In Russia and Canada it involves roof over you head and heat in winter. In most of USA it involves the car. In Central America you can do without car or heat.
