Actually, a high minimum wage hurts the community, in that it does not allow upward mobility, ie, first job, that we all want those youths to have. Again, it is the seen vs the unseen. We will never know how many youths who are capable and eager to work and learn will not get their first job where they can prove themselves.
Employers have an array of applicants of varying qualifications and experience to pick from when they advertise an opening. Why should they take a chance on someone who has never had a job and maybe has other strikes against him/her for that $13.09/hour job within the San Diego city limits?
