It is not due to tactics, though, that I refer to today’s troublemakers as “radicals.” I use the word here to mean those who seek to understand and change problems at their root. As civil rights icon and organizer Ella Baker put it, to think in radical terms “means facing a system that does not lend itself to your needs and devising means by which you change that system.” For really changing a society where a small elite controls most of the power and resources will not be easy. There will be a lot of resistance, and tinkering at the surface is unlikely to last. It is that understanding that drives the people I spoke to for this book, and that gives me hope that they might have an effect.
