Competition, not State versus private, key to productivity
Everyone in the United States empathizes with the sort-of joke from comedienne Lily Tomlin - "We don't care. We don't have to. We're the phone company!"
A 2018 survey by Yahoo Finance showed that Comcast, a "cable" company that provides television and broadband internet service to homes, is the most hated company in the US. Other telecom companies such as AT&T and Verizon Wireless in mobile phone service and Charter Communications and Cox in cable are always near the top of the "most hated" lists.
I was used to terrible service and abusive contracts from mobile phone service providers in the US, so I've been pleasantly surprised by China's three big telecom providers - China Mobile, China Telecom and China Unicom. There is good coverage nationwide, the prices are cheap, and service is quick and satisfactory.
