Assuming more people are hurt by deprivatization than helped, why would a local politician support such a policy?

Assuming more people are hurt by deprivatizaton than helped, a local politician would support such a policy as a politician is a part of the government. Deprivatization will lead to more control of the government on private firms; hence, politicians would be able to exercise their control over the firms. This would enable the politician to derive unfair gain from the company. Hence, a local politician would support such a policy.
