Privatization is all things to all people, but some of these goals are conflicting, and governments need to be prepared to sacrifice some in order to get others. For example, you cannot say you want high sales proceeds, high foreign investment, and low tariffs. Something has to give. Developing countries resent being pressured into adopting privatization policies. This gives more ammunition to the anti-reform forces.
Most politicians are reluctant privatizers.
Consumers are not bothered about economic philosophy they just want better service at lower prices. Often, sales proceeds are the least significant benefit, but the most difficult hurdle for politicians. All too often, the enterprise in question has a negative value when viewed by every valuation methodology except future potential. Governments should not go into the program expecting huge financial windfalls. Make unpalatable changes before privatization.
