Not sure about India but Japan is hanging by a thread. A conflict in Persian Gulf is enough to finish off its economy for example. Otherwise it would slowly die off. East Asia would just shine for a short time and fade into irrelevance and this century would be just another American century. US in its lowest point still manage to dominate the whole world and it‘s only a matter of time until it gets more competent leaders.Naah man, China is not Japan. China is nobody's puppet. I dare say that a screwed up Japan is doing way better than that Supapowar India. They have a fraction of the population and workforce, yet still maintain a much better overall economy.
Nobody in the real world shares your pessimism for automation. Automation works and it's gonna be the death knell of the overhyped, under skilled "demographic dividend" of India. After more than 11 years of Make in India, this nation still has a lower percentage of manufacturing in the GDP compared to Vietnam. This is shameful.
India has roughly a decade left to catch the last train to industrialization. After that, it's the middle income trap. But India's education system has been disaster, and not getting any better. It's current workforce cannot even compete with SEA in manufacturing.
With automation, SEA and East Asia will maintain a massive industrial lead over India. Companies would take automation over unskilled, undisciplined workers anytime. This is the harsh reality. India better get it's act together NOW. Stop bad mouthing other countries and start working hard. There isn't much time left.
Indicators only show that China‘s good times are over. It‘s repeatedly failing to achieve its consumption targets which will only get worse with an ageing population and its massive trade surplus would soon bring trouble abroad because other countries would do more to protect their industries.
