I have to plead ignorance about other countries. But in the US, I haven't really encountered too many developers who I sensed projecting superiority for the sake of job security. What I mean is that my impression is that they truly do believe they are a top developer. I have run into a few of those "job security" guys who are difficult to work with, but not that often. I think part of it is that it's easy to look at another developer's code which you inherit and judge it to be inferior to your own work. I have found this to be very common - the developer who is constantly griping about the terrible code they inherited. (I myself have been guilty of this). But, it can be more difficult to actually create the code - especially under time or budget constraints or requirements that change over the years. So, in that case it can be tempting to judge yourself as a better developer - when in reality you may have created the same crappy code or worse.
