Benzamide is less easily hydrolysed than methyl benzoate. Why ?

We know that N is less electronegative than oxygen therefore. N can donate a pair of electrons more readily than oxygen.  Therefore, magnitude of positive charge on carbonyl carbon in benzamide is less than in methyl benzoate. Thus during hydrolysis, attack of -OH- ion on carbonyl carbon in benzamide is difficult than in methyl benzoate. Thus benzamide is less easily hydrolysed than methyl benzoate.
