Back of the napkin math, assuming all 214,000 employees (Google result) are at $8.32/hr, and get bumped to $12/hr, and they all work 2000 hours a year (2 weeks off), that results in an annual increase in payroll of $1,575,040,000.
Obviously something has to change, and I don't think people would mind another bump in sale prices if that means better pay across the board for employees.
