Desperate Wives

The book in my hand, written in 1977, has acknowledgements that end as following:

"Finally, we wish to thank our wives for their tolerance of numerous working "weekends" and "vacations" during the past several years."

This was 1977. And still same (even worse) in the 21st century. This is pathetic! How many more sacrificing wives (and children) do we need to get to the truth?
