Lots of conservatives living in the sprawling public sector bureaucracy see all sorts of dysfunction and waste, then conclude "this is because government" rather than "this is because efficient management is delicate and difficult".
Lots of leftists living in the sprawling private sector feel the same way (myself among them) and - self-confessed naively - will insist profit motive is the reason bad policy exists, rather than simple human fallibility at industrial scale.
Also, public bureaucracy is something of a patronage system, with people getting their jobs relative to their social networks. In a big red state like Texas or Florida or Ohio, you can guarantee the local IRS office is going to be full of failsons and faildaughters of the Republican elected bureaucracy.
