Sure, you can replace brake pads yourself. But few people want to do it; let alone are capable. Saying "significant sources of income are therefore shrunk" significantly overstates just how many people would do their maintenance work on that level. I know people who have paid people to replace the bulbs on a car. My wife rarely even bothers to refill the washer and I can count on 1 hand the number of times she's checker her oil in the nearly 20 years of owning a car. Most people either don't care how cars work, don't have the technical capabilities to fix their own car or simply don't want to.
