No Internet, No cell phones, No faxes....No problem
Life just goes along slower than it does now. The problems remain exactly the same but take longer to develop and to be discovered by those involved. For instance, at the turn of the 19th century, it took months for news of who won a National election to be reported. Now we expect to know the results before the polls are closed. So what difference does it make really as long as everyone else in society is running at the same speed.
Typewriters and carbon paper copies with expert typists was the standard in the 1930s and 1940s. Now everyone is a typist with a word processor. Jobs and skills change as processes are speeded up.
