The minimum wage was never meant to be a livable wage. The minimum wage was instituted when the American culture was still dominant and the minimum wage was meant to be a standard for school kids, elderly people and jobs that required no education or training. It was simply understood that Americans would always try to better themselves through education and training because that was what defined America.
Presently, the liberal worshipped labor force in America now is the 3rd world, primarily Mexican culture, which believes that a minimum wage job is a career job and they do nothing to improve their skills or marketability to other employers, they simply take a job requiring no skills, stay there forever and whine that their employer doesn't give them enough money to live in the fashion they believe they deserve. NEVER does the thought of more education or training enter their heads, they simply demand that the liberal government help them take more from their evil employer.
It's a whole different culture than the American culture of self reliance, self determination and improvement.
