I once heard that in the middle of 20th century, public transportation in the USA was widely privatized and bought by automotive manufacturers, and then wilfully left to rot, so that people would buy more cars.
However, I can’t find anything backing that up. Do you know whether that’s true, and where I can find some sources for that?
Public transport is mostly going to be owned by local, state and federal agencies. I’d be willing to bet that what you read was written by someone that likes to make shit up.
