> Do you really think there's that many people willing to work between 18-25 and 54+?
And willing to work long hours at the minimum-wage rates required for US-based manufacturing ....
P.S. 18-25 and 54+ ... its actually 16–25 and 54+ I don't think you'll find many 16–18 year olds biting your arm off for a job in manufacturing either...
US average manufacturing average wage is $36/hr, which is far more than minimum wage.
