I think legalizing dope is a Really Bad Idea - but if you need more workers - pay higher wages.
Supply and demand. Part of the free market.
Employee wages is only half the equation.
Employers also known as managers, are incredibly UNEDUCATED. People and their enabling government falsely believe that you obtain the position then govern others.
Managers are quite incompetant, and competition weeds them out. Most bosses could not manage their own life, let alone another. You have to educate yourself or else fail.
