Minimum wage if raised, would pressure on employers to not hire the youth. With tiered system, firms have incentive to hire younger workers and fire unskilled older workers. Firms today discriminate workers based on job history/experience, so many of the youth have a hard time finding work. Tiered system is a win for the youth.
Unskilled older workers, if laid off, will at least have experience.
