I'm not advocating it as a solution for society, I'm just surprised that people would buy bunkers to help them survive the violence that they think inequality will cause, and not also think about taking steps to reduce the inequality by raising the living standards of those at the bottom. Both courses of action can be justified even at a self-interested level. There are lots of situations where groups have voluntarily agreed to abide by a code of practice in order to avoid having one forced on them by democratic government (or a mob). The concept is common enough that the Canadian government describe it here [1] It absolutely can work, as long as the voluntary code goes far enough and is adhered to by enough of the relevant industry.
