While work at Bell obviously slowed down since so little revenue was
coming in (the stock dividends were paid out of past surplus), it
Someone else mentioned 25% unemployment even in 1941. That is too

still very high but not quite as bad. It varied quite a bit by region
and industry. There were some nasty strikes in the late 1930s that
pushed up wages which allowed workers to have more money than mere
