Not true at all (I have team members in India). It is not even close to "roughly the same". For a decent engineer with 2-5 years of experience, you would pay anywhere from 8K-20K USD PER YEAR. That's average. Sometimes even lower than the 8K and sometimes higher than the 20K.

Indian engineers making more than 20k-25K USD Per Year are considered top talent in most companies across India. Are there engineers making more ? Yes absolutely. Are they a minority ? Yes, absolutely.
