President truman announced that september 2, 1945 would be

The end of WWII. When Japan finally surrendered the war was over. For the United States at least.

Ifound this on google “simply, the working conditions were terrible during the industrial revolution. as factories were being built, businesses were in need of workers. with a long line of people willing to work, employers could set wages as low as they wanted because people were willing to do work as long as they got paid.” i hope this you for what your looking for.
