RE: Why Don't We Respect Each Other Anymore?

You explained it really well, and I agree with you. The way people experience violence and inequality depends a lot on where they are born and the system around them.
Your examples of El Salvador and Venezuela clearly show that sometimes the present can become worse than the past when freedom, safety, and the economy break down.
And yes, your final point is the most important one: teaching empathy, respect, and humanity is one of the best ways to reduce violence in the future.
