GDP = Sum of value of all goods and services produced in a country. It includes:
1) construction - that encompasses cement and steel
2 logistics like aviation, railways, trucking, taxis etc.
3) services like banking, finance, insurance, tech, tourism, telecom etc.
4) industries like automobiles, electronics, home appliances, heavy engineering, ship-building, pharmaceuticals, petrochemicals etc etc.
Why not people compare production and consumption of various goods and services, tax revenues, socio-economic indicators, FDI inflows and all?
Why not compare the production of automobiles like 4-wheelers, 3-wheelers, 2-wheelers, tractors and even agro machinery? Why not compare production of heavy construction equipment? Why not compare heavy engineering equipments production? Why not compare production of industrial machinery? Why not compare production of textiles and footwear? Why not compare production of steel, cement, aluminium, copper and other metals and stones? Why not compare petro refinery throughput and production volume of various petrochemicals including plastics and agrochemicals? Why not compare production of locomotives? Why not compare production of various pharmaceuticals, why not compare the production of electronics goods and home appliances, why not compare consumption of telecom services and production of telecom equipment? Why not compare office & retail space and warehousing inventory and it's annual absorption? Why not compare hotel key inventory in India? Why not compare mining sector output? Why not compare energy production and consumption? Why not compare production of energy generators like solar modules, wind turbines, diesel generators, electrolysers etc and related equipment? Why not compare total passenger air traffic and cargo movement at Indian airports, and MROs? Why not compare ridership and cargo movement volume of railways and public transport along with it's revenues? Why not compare gross tax revenues? Why not compare revenues generated by Financial (Banking/NBFC/Insurance/Fintech/Brokering) sector? Why not compare revenues generated by ITeS, data center, consultancy (big 4 for ex) and GCC sector? Why not compare production and consumption agricultural goods or basically anything, heck even weapons and defence equipment, compared to other countries and especially India itself, both today and back when we gained freedom and independence?
And when you do research for the above, do research for the projected production volumes in future. Sure the list is long and this post will sound boring and stupid to others, but this right above covers almost the entirety of the Indian economy. For ignorants stuff like these are mere products and commodities and for them barely holds any value to an economy and hence can't comprehend and imagine their importance.
The day Jeets actually start looking for the stuff above, like I like to follow, they'll get a reality check of how badly impoverished India was as recently as 2 decades back, leave the shitholery during independence when western world was wealthier than it is today and where does India stand today w.r.t rest of the world, and where will we stand in future i.e. 5 years, 10 years, 15 years from now. Start by learning what economic complexity means.
