In 1985, Mikhail Gorbachev, launched an ill-fated anti-alcohol campaign in the then Soviet Union. The anti-alcohol campaign had some beneficial public health consequences: Crime fell and life expectancy rose. But the campaign was a political and economic disaster. Gorbachev forgot that the addiction of the state to alcohol revenue was even more incurable than the addiction of some citizens to alcohol itself. The budgetary losses created an economic crisis. Historians suspect that more than the loss of the Soviet Empire, it was this campaign that delegitimised Gorbachev. An old Soviet joke went like this: A disaffected and angry citizen, fed up of standing in lines for vodka, decided to go assassinate Gorbachev. He soon came back and ruefully reported that the lines to assassinate Gorbachev were even longer than the lines for Vodka. As the lockdown eased in India, and social distancing went for a toss at alcohol outlets, we were reminded of how difficult an issue alcohol is to rationally discuss in India. The stampede was caused by the ineptness with which the opening was handled in most cities. Alcohol has also migrated from being a question of personal freedom and choice to an issue in broader cultural wars, an odd site on which we measure progressivism in India. It is also a window on how liberalism has been misunderstood. Liberals should, rightly, be suspicious of prohibition on moral and practical grounds. Government grossly exceeds its legitimate power when it interferes with the rights of individuals to lead their lives as they please, and fashion their selves after their own ideals, interests and preferences. And certainly, moralism or puritanism on alcohol cannot be the basis of state policy. That moralism has no basis, and it violates the dignity and freedom of individuals.
