The african american neighbors are extremely obese and _constantly_ eating McDonalds (I can tell from the litter I clean up in the parking lot...). My ghana immigrant neighbors on the other hand are skinny as rails and can be seen hauling 10 pound bags of rice/beans/etc. into their house.
It's often overlooked, but there's more than just money that passes between generations. Simple knowledge like "how to cook with unprocessed foods" is extremely valuable information to pass on to offspring. We need to somehow tackle that if we ever plan to help people entrenched in inter-generational poverty.
