The relationship between minimum wage and teenager's employment

When the minimum wage is raised, it can be expected that teenagers (rather than members of any other age group) who are most likely to lose their jobs (or get turned down for employment).

In general, teenagers are not skilled and have less experience of the work, which requires the employers to put more time and effort to training them. If the minimum wage is raised, the employers would reduce the spending. The first thing they would consider is to reduce the spending on hiring staff member. They will be more likely to hire skilled employees who can deal with more job tasks rather than unskilled workers who need to be trained. From this reason, I believe that increasing minimum wage would not allow teenagers to keep their job.
