While a bad CEO will be shown up quickly by his results, and can hopefully be replaced in time, changing a bad owner is virtually impossible. That's the trouble with holding on to public sector units. With the government having managed by hook or crook to have shaved off over Rs 12,000 crore from its divestment deficit with the help of the poorly planned and even worse executed sale of ONGC shares, the upcoming Budget session may see little dust or debate being kicked up over the issue of the government's disinvestment policy, and what it hopes to achieve by it. Which would be a pity.
