尽管民主国家很少互相争斗的说法已被广泛接受，但关于为什么存在所谓的民主和平的共识却很少。 一些批评家认为，实际上是工业革命导致了19世纪和20世纪的和平。 由此产生的繁荣和经济稳定使所有现代化的国家（民主国家和非民主国家）彼此之间的交战要比工业化之前的交战少得多。 现代化引起的几个因素可能比仅民主制对工业化国家产生了更大的反战感。 这些因素包括更高的生活水平，更少的贫困，充分的就业，更多的休闲时间以及消费主义的传播。 现代化的国家不再只是为了生存而需要相互支配。
新加坡国立大学政治学论文代写：民主制
Although the argument that democracies rarely fight each other has been widely accepted, there is little consensus on why so-called democratic peace exists. Some critics believe that the industrial revolution actually led to peace in the 19th and 20th centuries. The resulting prosperity and economic stability have made all modern countries (democratic and non-democratic) fight with each other much less than before industrialization. Several factors caused by modernization may have a greater sense of anti-war than industrialized countries. These factors include a higher standard of living, less poverty, adequate employment, more leisure time and the spread of consumerism. Modern countries no longer need to dominate each other just to survive.
