I think you're mixing up annual and monthly salaries/employee expenses. At 666K/month the 3 "well paid" workers are costing 222K/month and the 20 "poorly paid"

I think you're mixing up annual and monthly salaries/employee expenses. At 666K/month the 3 "well paid" workers are costing 222K/month and the 20 "poorly paid" workers are costing 33K/month. I'd be rather okay getting paid this poorly! I like where you were going with your comment but the math doesn't support the specific argument.
