This defines a visionary moment as the country chooses 'pooled sovereignty'

The tax reform is expected to transform the business landscape but will test India's weak administrative capacity © AP There are rare moments when a nation will do the sensible thing despite itself. Such a moment will come this weekend when India introduces the most far-reaching tax reform in its history.

Indians have a saying that captures the tendency of family businesses to decline over generations: “The life of a business house is 60 years.” This phenomenon was portrayed by the German writer Thomas Mann in Buddenbrooks, his novel about a wealthy merchant family in the city of Lübeck whose business disintegrates as the children lose an appetite for making money. Until now, the 148-year-old Tata Group has defied this rule.

Last week India sent a satellite into orbit around Mars,with a low-cost, nimble mission that has stunned the world. At $74m over three years, the cost was roughly one-ninth that of the latest (also successful) US mission, which took six years. And in reaching the red planet on its first attempt, India’s space agency succeeded where many other leading powers – including the US, Russia,China and Japan– failed.

When the Indian government presented its budget last month, the people were expecting giveaways, subsidies and bribes for votes. But it turned out to be a surprisingly responsible settlement that capped the fiscal deficit at 4.8 per cent of economic output. It was a sensible budget, but it will not get India growing again.

India's mystifying economic rise bewilders Indians and baffles economists. No one quite understands why this noisy and chaotic democracy of a billion people has become one of the world's fastest growing economies. It is looking at a fourth year of consistent real growth of around 8% a year, following upon 22 years of very respectable 6% average annual growth. What puzzles economists is that India is not following any of the proven paths to success.

The Chinese premier's recent visit to India was a good thing because it took our minds off Pakistan, even for a fleeting weekend. We really must learn to ignore Pakistan and heed China. If Pakistan pulls us down into an abyss of terrorism and identity politics, China will lift us up, I think, firing our ambition for better roads, schools and health centres. I used to either admire or fear China, but now I am more relaxed. Both our economies are among the world's fastest, and both are on the verge of solving their age-old economic problem.
