Sure, I misread your point. Such burgers
do exist, and I thought you were talking about those.
For sure, efficiency is part of "working". I guess my baseline for "working" is a far lower level of efficiency than yours.
Yours is certainly contextually-relevant to our society (ie., we should always hope for better efficiency). But I think when taking a step back to answer the binary question "does government work?" our baseline has to be against governments which dont (rather than some minor local inefficiency).
Governments which don't work produce civil wars, mafias, mob patronage structures, impoverished citizens, etc.
It is those governments we shouldn't trust, rather than a somewhat incompetent western bureaucracy which should mostly get the benefit of the doubt towards "working".
