So many of our causes, passions, and movements could be characterized in terms of David versus Goliath, requiring superhuman strength to set right. At the outset, the odds are stacked against us. Business corruption must not be allowed to metastasize, lest the country be utterly eviscerated by it. Environmental pollutants must not destroy our fragile ecosystem. The military must have its spending curtailed in order to prevent massive waste and a swelling national debt, a belief held even by those who do not object to the very existence of a military. The prison-industrial complex must not be allowed to grow ever larger, while it incarcerates men of color at rapidly growing rates. It’s easy to get burned out, knowing the vast size and sweep of these problems, and easier still to believe that no amount of effort expended for any length of time will make one iota’s worth of difference either way.
