The Second Indochina War impacted Vietnamese people socially in a number of ways. Some of the more important include:
The North was deeply affected by the war as people in the North were called on to make tremendous sacrifices. Northerners were asked to accept severe reductions in their standard of living as resources were dedicated to the war. This was exacerbated by the impact of the bombing on the North.
In the rural South, it was very difficult for farmers to live the way they had. The war went back and forth across their land. The Vietcong demanded tribute. The South did things like rounding farmers up into the “strategic hamlets.” All of this changed life for Southern farmers.
In the capital of Saigon (and in other places to a lesser extent), the presence of the Americans changed society. The Americans came with huge amounts of material wealth. This led to the creation of a black market for American goods. The black market enriched a new set of Vietnamese who were able to make contacts among the Americans. It also brought more in the way of prostitution and drug dealing to the Vietnamese economy and society.
