You are wrong , In India education is highly subsidised. 4 years IIT B Tech will at most cost 5 Lach Rs . (Tution Hostel Books Personal expense such as PC or Lap top) You send your kid to US, it will cost you 15 lach rs per year.
If your child is US citizen, even than it will cost Rs 6 lach per year. (Mind it IIT cost I am saying is per 4 year)
And if some one has 3 or 4 children ready for college education it is his/her problem. Not of GOI.
