I respectfully disagree: First, concerning government involvement... Historically, there have been many times where the private sector was unable or unwilling to provide a decent quality of service at a reasonable price and government involvement was required in the public interest. Unfortunately, some problems gave government regulation a bad repuation, and "deregulation" is the popular theme of the day. (Deregulation also allows certain players to make lots of money.) Since Divestiture of the Bell System, new technologies have developed, and some of them have allowed the communications network to be compromised in a bad way, such as fraudulent sales calls. In my opinion, it is clear that we need some reasonable regulation to protect individuals. Second, concerning the content of many robo calls... A great many of the calls are perfectly legal because Congress said so. I think the telecom industry is basically very happy with this since they profit from selling equipment to make the calls, and transmission facilities to carry the calls. Unfortunately, Congress does not seem to care about protecting citizens these days, and has even introduced bills that would allow things like sending sales calls to cell phones, even when the recipient has to pay for them.
The general public has to stop being lazy and actually give some thought about who is running for office and vote for the best people. Third, as to ignoring robocalls... There is no law that says you must answer the phone. But the reality is that telephone and robot-calling are being used today to transmit critical information. It would be impractical for a municipality to have a human call every single resident to warn them about an impending flood, utility problem, etc. As to other callers, like it or not, robo calling saves them money and many businesses are exploiting it.
Someone else suggested that the telephone was obseolete. I don't agree, indeed, I think some new uses are very beneifical to us.
