In Britain the cs are basically providing long-term continuity regardless of how chaotic and volatile party politics becomes. What we see is that most of the machinery of state keeps working, despite the circus in the Commons. Despite Covid. Despite Brexit.

Most people's contact is through online, if you can fire up even the most basic browser almost every interaction is clear, fast and smooth.
When you start dealing at a higher level (business and contracting) then you see behind the Wizard of Oz's curtain a bit. Things go more smoothly if you have the right documents and history. Isn't that the same in every country though?
So, it serves regular citizens very well, but less considerately as your needs are more complex. Effective maybe, but I didn't say "fair" :) Certainly there must be many people find it harder, and I'm probably showing my privilege.
