I think the breakdown here is that conversation seems to have no power. To only be a bit hyperbolic, the only language with power is money -- or violence. To the extent that ordinary people cannot make change with "conversation" (which I interpret here to mean dialog within society, including with lawmakers), they feel compelled to use violence instead.

A non-rhetorical question: What recourse to non-billionaires have when conversation has less and less power, while money has more and more, and those with money are making much more money?
