Do you think higher MP DX cameras require better lenses & technique?

This is a good question and a claim i've seen many time...xx MP will requere better technique then yy MP.

I cant find any way how that'd be the case. If someone has some supporting evidence / theory of why this migh be the case  (other than personal account shooting with different cameras - too many things can be different in an uncontrolled scenario), i'd love to hear about it.
