How does the government not helping those in need lead to the Great Depression.

Basically if you are a king or queen, and you don't help your people when they are having issues whether it is financially or other, they would fall into poverty. That is what happened during the Great Depression when the government did not meet the needs of their people and that led to  poverty for most of America. To not look out for someone is neglecting them and that causes many deficits in many factors.

the best description of postwar writers might be progressive.

following the war, writers showed a tendency to work on artistic or social matters rather than political themes. while postwar literature may not have been the greatest period of english literature, the themes provided excellent critics a high number of novels. such examples include anthony burgess, anthony powell and frank kermode, all of which can be placed under the progressive view.
