The country is run by two extremely busy people who's core competencies lie in politicking only , who more importantly have very shitty and Low IQ advisors.
Also there's the fact that Modiji is very averse to creating new PSUs or PSU JV with foreign companies/ Putting GoI funds even for a "strategic" purpose such as this, Private sector is full of penny pinching banias who want everything on a platter, ez profits and will never take risks, so a private sector corp building and running a fab is out of question.
TSMC itself is a result of the then Taiwanese govt catching the feet of some hotshot Chinese Semiconductor/IC guru who was settled well and making big bucks in US, they somehow convinced him to come back to Taiwan and lead the project that would eventually produce TSMC along with other very famous companies, the very first of such facilities was called "Hsinchu Science Park", So you see Govt interest, support and funding is very essential for capital intensive undertaking like a Semiconductor Fab
Don't forget how it all started Chinese caught on to late transistor era we missed it. They started out by manufacturing light bulbs, chargers, toys, and every kind of cheap electronics that you can imagine. The one that had quality were sold in western market in the late 2000s but majority was sold to third world nations. Eventually their transistor base helped them further into Microprocessor era and by luck they have one of the largest semiconductor raw material reserve.
But the biggest factor here was the government, they handheld the industry in its nascent stage everything from cheap loans, land, water, transportation, Power was taken care of by the government.
Now imagine the Indian scenario a common block level clerk asks for 500 ka note for issuing domicile, imagine a industrialist approaching the government and babus. People here say why don't industrialist innovate, well who would spend money on R&D when their is no one apricating it. We know what happens to those who innovate i.e., Tonbo.
Have you seen how Germany treats Volswagen, Dialmer, BMW comapre that to how we treat ours.
The Run down OFB is asking 5 Billion for upgrades, Air India is in constant loss, BSNL is limping on its last leg, all major PSUs are racking debts.
Babus are fleecing money from the economy, a junior engineer in my place was caught with 30 crore. Roads We build break down, Drains we build are washed down, bridges we build break down. and u know whom to blame for this. My friends brother is an IES and he says "Bode me bhar ke paisa ata he" such is the height of shamelessness
I expected massive overhauls in bureaucracy when Modi came to power nut 6 years later he is still deepthorating the collector jee.
We glorify this British era relic too much. British used civil servants to keep the Indians in check and now they are used by politician to keep us in check.
ye log mil ke khoon chus rahe he apna.
Modi believes he can deal with the Bureacrats like he did in Gujarat but wo log state level ke madharc*od the ye log national/international level madrac*od he.
70 years we experimented with Socialism and bureaucrat for once give Capitalism and technocrats a chance. Get out of the comfort zone for once.
