If you look at walmart for example, and entirely eliminated the compensation of the CEO (19.4 million), and all executive vice presidents and CFOs (2.8, 10.8, 8.4, 10.1, 11.5, and 8.5 million respectively) and total them all up you get ~$71.5 million.
71,500,000 / 2,000,000 million employees = $34 dollars per employee per year of a raise. That's almost negligible, and if you assume minimum wage (7.25) 50 weeks a year, for 40 hours a week gives $14,500 / year, you get $35 / $14,500 = a .24% raise. That's less than a 2 cent per hour raise per employee if you completely slashed the salaries and compensations of the top executives.
