Don't forget: Google etc already gets a ton of criticism for their use of manual screening as it is - it burns people out, gives them 'PTSD', is exploitative, etc. So to account for turnover, psychiatric healthcare benefits, extra salary (remember overhead is as much as salary), and figure you would have to double that cost to eliminate criticism (not that it would but let's say it did). That actually would be larger than Google's total profits.
