The ratio itself isn't the problem, it's the assertion that we need a growing amount of administrative vs. procedural employees. We can talk in hand wavy abstractions all day long, but for every additional person you have to pay who isn't _writing software_, you need to now pay that much more for your marginal cost of obtaining the software. In almost every other modern domain I can think of as well, efficiency is moving in the other direction. (I think, if I'm trying to be formal here, some aspects of this would seem to be described in 'Baumol's cost disease')
If we're talking anecdotes, from what I've seen of administration in healthcare and military (family is in that business) and at bigCo (my business) we could likely handle a far more lean ratio of knowledge to support workers, but that often goes against leadership incentives/risk tolerance for less conventional strategic decisions. (although I think we're seeing vestiges in this through the pushes for e.g. devops and dev/test merges)
