Why is the metallic atom in low oxidation state in metallic carbonyls?

The metal atom in metal  carbonyls is in low oxidation state. This is because if the fact that there is a higher electronic density (electronic charge) on the metal atom in its lower oxidation state than in its higher oxidaton state. Thus, since the metal is electroposative in nature, it would feel more comfortable if some of the excess electronic charge present on the metal atom gets transferred to the vacant pi-orbitals of CO (ligand) by forming M-CO pi-Bond.
