I've actually read 'The Talking Cure' before, for something I did in undergrad. It was just as good the second time around, and something I especially like about it is that it acknowledges how exhausting it is to keep up the level of communication that is shown to be necessary for development. Poor families often don't talk to their kids as much because they are already over-exhausted from the amount of labor they have to do to survive. This connects to the ideas presented in 'How to End Extreme Child Poverty' - and it's always funny to read articles about child tax credits for me, because so many other countries already have a permanent system in place pretty much along the same lines. It's pretty simple - to end poverty, you give people the means to survive. To end homelessness, you give people homes, etc etc etc. But more to the point, if parents have the means to survive, if they are given help to raise their children (because the understanding that child-rearing is a community obligation was implicit for the vast majority of human history, and the nuclear family is an extremely new invention), they will ultimately be more successful in that endeavor.
Anyway. That was basically a long-winded way of saying that capitalist, individualist economic systems are in direct conflict with best child rearing and development practices. :)
