If this were on almost any other thread, especially one focusing on the particular topic, the K-12 system would be shit on too along with the roads and post office. The only one of those that arguably reliably beats private services with similar level of funding would be water utilities, and that's partially because water rights in the Western US are a legal quagmire.
You missed the point that was made. The point wasn’t that government is efficient or good but that the experiences with the IRS and DMV don’t account for the sentiment toward government services in the country. The person I responded made a claim that interactions with these two services explain the attitudes people have toward government. I think that is an overly simplistic explanation.
