Inflationary price changes over the last 5 to 7 decades (post independent India) would easily justify the prices for the goods and services. That "septic tank story" in the OP is true in every country. The price of service should include how difficult/distasteful/dirty the job is, as well as the other components of benefit the customer gets. Here is a brief episode called "auto-biography", where the characters talk about cars, and interesting life-snippets with their cars. Winston Rothschild, recalls his younger days, when he had used a Ford station-wagon, to service septic tanks, and haul away the refuse, before his business grew, and he could get a real septic tank pumping truck on EMI loan. I am sure his prices for the service went up too. On the positive side for the pensioners on fixed income, it is a good thing that the septic tank service happens only once every few years.
