How is this somehow the fault of “capitalism”? Regardless of how the system is structured, the government has a near-infinite budget, they could theoretically staff the agency with enough people to answer my call in a timely manner. They could also train their staff to treat me with human dignity. They don’t do this, and the reason is that they have no incentive to do so. If I am upset by being treated poorly what recourse do I have? Nothing. In fact if I ignore their system long enough, armed goons will show up with guns and arrest me.
There are many examples of government agencies that have this reputation, not only in the USA but the entire world.
