Remember that the vast majority (around 95%) of people never buy another lens after their original purchase of a DSLR.
I'd love to know how someone can generate such statistics. I mean, you can't correlate sales figures, because you have no idea whether people are buying a body to replace an existing one or buying one fresh. And you can't even assume that people who buy one with a kit lens are new buyers, because they might turn around and sell the lens on eBay at more than the difference in price between the kit and the body-only price, or they might be buying the kit lens to have as a "beater" lens for when they go to the beach or whatever.
Also, even assuming the whole "people don't upgrade" thing is true for entry-level bodies, the main reason for that is because lots of people buy them, try them, conclude that they can't deal with the size and bulk, and go back to shooting photos with their cell phones. That doesn't mean that someone who actually plans to shoot for more than a week with a DSLR shouldn't choose a camera based on what lenses are available.
Also, to the extent that the "never upgrade" thing is true, it means that the manufacturers need to improve their kit lenses, because a lot of folks won't upgrade, and will be daunted by the low-quality images that they get compare with what they were expecting. This leads to people giving up before they find a reason to buy a better lens.
Probably not 95% if Canon production statistics can be used as a guide. In April 2014, Canon surpassed 100 million EF lenses. In February 2014, Canon produced its 70 millionth EF camera (film and digital).
