I find your article very much relevant because the curriculum is objective oriented whereas life outside is very much subjective oriented. Excel spreadsheets are only 1 means but one requires human nature to cut through the corporate ice and this nature I don't think any b-school develops. As a leading management thinker from the USA put it - Listening is strategic, everything else is tactical. One must develop listening and awareness skills - my experience from b-school as well as a leading Indian corporate house has been otherwise.
Good that you have put forth a message - perhaps b-schools should only recruit after a person has gained some vitakl work ex to relaise how theory can meet practice.
