Bilal, I sympathised with some of what you wrote in the post I quoted (about being able to critique one's own country) but this line of reasoning is silly.
Your original point was about how I benefited from having a banya like Bajaj manufacture motorcyles. Perhaps you wanted to drive home a point about how we benefit from a PSLV launch but choosing a motorcycle (and now cars and buses) as an analogy is quite poor.
While there is something to be said for arguing that benefits from a launch vehicle are not immediately tangible and the odds are high that average citizens will not gain anything from the PSLV, motorcyles and cars are very different products. As per the 2011 census 20% of Indian households had some form of motorised transport - mostly two wheelers - like the ones that Bajaj manufactures. Without people like Bajaj making these products these 20% would have a transportation problem and that in turn would make their lives less productive and in many cases reduce social mobility (like a rural kid who would not be able to bike it to an urban college). As a teenager growing up in India in the 90s I often got a ride to my school on our neighbour's bajaj scooter. On Sundays my dad would drive us all out somewhere on his Bullet (a motorbike). In college my roomate had a second hand Hero Honda bike and we used it frequently to get to movies, take girls out and buy booze from a shop that was quite far away.
To answer your question: Am I "benefitted if Bajaj makes motorcycles" ? The answer is a big fat Yes. Without Bajaj I'd have to take some public bus, suffer a crowd, loose time, get turned off from going distances and have a poorer quality of life. If Tata did not make buses, there'd be no public buses either and I'd probably have to walk. Is Bajaj making a ton of money - sure he is. Would I rather he and I stay equally poor? Nope. I don't mind him making money if I get the opportunity to buy something useful - as opposed to not having that opportunity. Furthermore, being a banya, Bajaj will use some of the profits he makes to set up some new factory - for locally made sewing machines perhaps or tractors - and then some other family will be able to improve their quality of life. If the government makes money some of that will be used to build a flyover or a metro or something else. Will corruption eat some of that - sure it will - but a reality with no bajaj would also be one where no such money (for the govt.) was available - versus the current reality where at least some money is generated.
I sometimes read about Pakistan where the automobile sector has not taken off and think - there are so many middle class Pakistanis who are stuck with having to buy the Suzuki Mehran for want of other options - that too at a ridiculous price for an obsolete platform. Would not their lives be better if some Pakistani Bajaj made an affordable modern car at prices comparable to what latest cars are sold here in India? Of course it would. If someone like you was in charge Suzuki Pakistan would be wound up - and nobody would be able to buy a car anymore.
By your logic - nobody should be manufacturing anything or providing any service - and we'd all be living in the stone age.
. One needs to keep the focus on development ignoring distractions and that requires focus of another Level. Status quo will be a huge distraction.
