>your retirement plan must involve children or some community inheriting it and taking care of you in your old age.
My farmland pays a rent dividend on the order of 2-4%/yr and I don't even have to be there or even show up to collect it.
I bought my farmland because I consider it doing my part to preserve the planet. I'm a big believer in the future of locally produced food and more local communities in reducing emissions and _corporate wastefulness_. As a side benefit it will preserve my standard of living. I thoroughly enjoy steak and so do a lot of other people. Livestock, land, and gold have preserved wealth since ancient times.
