The postal service - for some reason its existence has become political now and it makes no sense because it was always able to be self sustaining until Congress poisoned its ability to function economically (happened in the Bush era, Democrats had the numbers to save it but helped poison it instead - exhibit 23,546,568 how Democrats are useless)

TLDR if you need to get an object across the country, they will do it for a few bucks and I think that's pretty amazing
