Europe has among the lowest food prices in the developed world. If you spend 3-5 EUR on ingredients you get a really healthy meal... Agricultural products are usually taxed below 10% and the agricultural sector is heavily subsidized; I would suspect that farmers in India live closer to the poverty line than in Europe - maybe that explains part of the differences for prices of raw materials; supply chain certainly is another: it’s true if everything is bought as locally produced the costs might be lower because no transportation, cooling etc. is needed... But kindly also do not forget food safety: I never had food poisoning in Europe - India is a whole different story... In Europe, drinking water comes out of the tap for free, electricity is super reliable and veeery cheap... Farmers in Europe do not have a history of committing suicide at scale...
Dumpster diving is not a big thing and it is simply incorrect that half the products are thrown away... People in Europe are generally very sensitive to food waste and the infrastructure we put in place to keep it fresh is pretty decent.
Democracy in Europe (and other places) decided that it is justified to “take money disproportionally from society” because “majority vote justifies that 20% of population need to pay for 80% of costs”. I may not like this aspect of democracy (e.g., majority gives always a justification over whatever you want to do) but well...
Indians might want to understand that Europe see taxes as a way to create a liveable and fair society. That the need and desire of the individual sometimes is not as important as “the greater good”.
In India, the rich are certainly not subsidizing the poor. If I am not mistaken, your “elite” keeps 2x India’s GDP hidden away in Switzerland still? The Swiss offered help - but your government refused and felt the money better stays where it is.
The society you see in India is the society Indians created. I would not trade it for Europe ever.
