Final answer:
Increased access to education is the option that supports the idea there will be less violence in the next generation, as education can lead to reduced violent tendencies by fostering critical thinking and empathy.
Step-by-step explanation:
The question about what supports the idea that there will be less violence in the next generation can be answered by looking at the options provided and understanding the root causes of violent behavior and how they may be mitigated.
The most supportive idea for a decrease in violence in the next generation is increased access to education. This is because education often promotes critical thinking, empathy, a better understanding of consequences, and provides more opportunities for individuals, which can collectively reduce violent tendencies. In contrast, the other options are traditionally associated with either an increase in violence or have a complicated relationship with it. For example, rising income inequality can lead to increased crime and violence due to frustration and lack of legal means to improve one's situation. Lack of social support systems often leaves individuals without resources to cope with stress, which can lead to aggression. And while media portrayal of violence has been associated with aggressive thoughts and desensitization to violence, thus potentially increasing the likelihood of violent behavior, significant research debates the strength and nature of this relationship.
