Not sure if a contrast between "base infrastructure" and "apps" in response to "only on webapps" is supposed to be a joke or not. Just because its not a webapp it doesn't mean it's "base infrastructure".
The rule of thumb is that the vast, overwhelming majority of developers are working on business apps, especially Line Of Business (LOB) internal apps nobody ever sees.
It's hard to get exact numbers for this stuff but I wouldn't be surprised if the ratio of base infrastructure developers (kernel, shell, drivers, compilers, runtimes, frameworks, libraries etc.) to app developers is 1:100.
