Here is a quick explanation of why the system is so broken (especially in the US).
There is an ongoing conflict between the Leftarian take-care-of-everyone-so-we-can-get-on-with-things philosophy and Rightist social Darwinism and power-for-its-own-sake.
We (the Left) set up systems to take care of people; where the Right can't outright destroy them, it renders them as ineffective and punitive as possible -- because egalitarianism is bad, and disempowering the lower classes so they will be desperate to serve the powerful is good. If some of them die in the process, that's even better, because it culls the herd of outliers and rebels, and makes the rest more likely to fall into line, which improves the bottom line.
I wish I was exaggerating.
