MUMBAI, Dec. 21 -- Union minister for commerce and industry Piyush Goyal on Saturday declared that the country was "firmly on track to become a USD 30 trillion-plus economy by 2047". He was speaking at the World Hindu Economic Forum in Mumbai. The minister outlined what he called the three core pillars of India's growth strategy under the current government. "The first pillar is public welfare," he said, claiming that large-scale initiatives in housing, sanitation, food security, electricity, water supply, healthcare, education, and digital connectivity had "ensured that basic needs are met for citizens". The second pillar, he said, was infrastructure, pointing out that India had seen rapid expansion in highways, airports, railways, and digital networks. 99% of Indian Railways was now electrified, "improving efficiency, safety, and sustainability", he said. The third pillar was innovation and enterprise: the government, Goyal said, had focused on reducing compliance burden, improving ease of doing business, and promoting research, all of which "encouraged entrepreneurship and job creation"....
