This is incorrect.  The marginal effect of education would still be 
estimated as the coefficient on education regardless of the values of the 
other variables (there are no interaction terms).  You are confusing the 
point estimate and the marginal effect.

Please refrain from posting if you aren't fairly certain of your answer.  I 
also think the list may be indulging too much in answering very elementary 
statistics questions which have nothing to do with Stata directly and can be 
answered through many other available resources other than Statalist.
