So do you think Pvt sector India building it's own gun and not passing foreign maal as there own?
What is there to believe?
You argue like an idiot.
You are giving cradit to PSU for literally doing nothing but acting like a middlemen.
While you have problem with Pvt companies doing same work in fraction of cost and significantly better quality. Do you know majority of upgrades done now a days are actually done by same Pvt companies like L&T, TASL,Godrej Aero and dozens of other small companies ?
PSU except from few like BEML and BEL are utterly incompetent for any kind of work except May be routein repair and maintainance work. Don’t believe me? Check for the contracts awarded by IA/IAF/IN for upgrade/overhaul in last five years
Anyway Pvt companies tend to invest in the tech so that they can make profit. PSUs don’t because their job is going nowhere even if they do nothing in the hole financial year.
Try to understand it by taking example of BSNL. you as a customer don’t want an inferior service/product at an exhorbitent price. Simply switch to Airtel Jio or Voda whatever give you the best bang for the buck.
One more example is Auto sector.
No one buys HM Ambedsador anymore when you an get a Honda city or Hundai Verna at the lower price. (Or Tata harrier and Mahindra Alturas)
Anyway it first matter if the original designer is foreign (foreign mall as you say)as long as the IP is owned by the Indian company and the company is competent enough to improve on that design over time and learn from it to develop newer products.
