For some real insight on root causes check out Locust Effect by Gary Haugen, someone who is now a couple decades ahead of where you are, who has made a real, tremendous impact in the world. What you may see is the cause is actually deeper than you think - meaning the solutions must go deeper.

Ultimately, we can't legislate basic human goodness, and there will always be those who take opportunity to exploit the vulnerable, so solutions must remove the core causes of vulnerability. Politics, unfortunately, just tries to declare things into being and rarely understands the systemic interactions at work, and often is actually driven (on all sides) by those who leverage their own positions as a form exploitation for their own agendas. It's easy to get everyone to agree that we should make the world a better place. It has proven impossible thus far to get everyone to agree ideologically to 1. What is actually better, and 2 by natural transitive property, How to get there.
