I'm going to call this a lie in many cases. For the most part, at least in my experience over the last 40 years, the USA has evolved from businesses having people answering their phones in a timely manner to the above. I'm sure there are variations of this, but my impression is that businesses are no longer properly staffed, they don't want to pay for employees to answer the phone, would rather have you hold, or you end up talking to someone in India, the Philippines or Asia where they are paid relatively less.
