This is an important, well-written, accessible and critical book which seems to have flown a bit under the radar, which is an absolute shame. One of the things we need to really focus on going forward is thinking of ways to find alternative systems, rather than figuring out ways to retrofit half-baked adjustments into existing systems which are fundamentally broken.
In Margulies' paraphrased words, the patchwork system of nonprofits, government and quasi-governmental systems which control development and investment in most "low income" communities these days seem more interested in trying to make it easier for people to survive (not thrive) in the neoliberal system we've built for others -- rather than finding other ways of living and thinking that could fundamentally lead to better outcomes for more people.
For Margulies, the most readily apparent alternative is a massive expansion of community land trusts. I'm not an expert in this realm, but it seems reasonable enough to me, and for what little I know, I know they work at least in small scales. I think this is a strong, compassionate argument and an excellent contribution.
