India cannot be compared to usa
USA is a hyper power the worlds greatest military with global power projection.
Who is comparing, I gave you an example. Take present Russian Airforce for instance
Mig 29/35 -- Air Defence and Multirole
SU 27/30 SM -- Heavy Air Defence
Su 35 -- Air Strike
Su - 24/25/34 Pullback -- Ground attack Bomber
Su 25/35 -- High altitude Recce
Tu 142 -- Maritime recce and strike
And in future
Pak Fa -- Air Defence
Su -35 -- Strike
Su 34 Pullback/ Pak DA -- Long range Bomber
Su 35 -- Recce
Mig 35 -- Multirole
Su 33 -- Carrier based combat plane
Take Chinese
J-22 -- Air Defence
J-31/Su-35/J16 -- Air Strike
J-10/ Su-27 -- Multirole
J-15 -- Carrier based
Su 30 -- Maritime role
Tu-22m -- Maritime Recce
An Airforce, which have 400 combat plane in its inventory, should stick to Multirole combat plane, which will reduce the infrastucture, training, and spares. Role based combat planes are specialized planes for a specific role but now with the technologies for the Ground attack cheaper Light PGM, kits, and A2G cruise missiles are now available.
For India, IAF wanted to induct Multirole Mirrage 2000 H in large numbers, but due to economics constrain, and unknown reasons, the congress goes for MIG-27, Mig 23, Mig 29 B, Mig 25, and Jaguar IS/IM. A good decission could have been SU-25 instead of MIG-27 with full transfer of technology to HAL for Bomber, Instead of Jaguar IS/IM mark 2 version of Marut, and instead of MIG-23 and MIG-29 B, Mirrage 2000 H in numbers, which could have been easily upgraded to Mirrage 2000 UPG, and could have relief the pressure on the LCA.
