Last week I saw this documentary and you can watch it through different eyes.
I think a lot of how we can live self-sufficient but on a way that it is also attractive for families with children. You don't have to be a hippy if you want to live self sufficient.
I think that the average people remember the bad site of this documentary. That is that communities fail after a while. I think this is not truth, when people work together with clear rules it will work.
The trouble start when people want to own land.
The solution is what they do for farmers in Russia, this also work for families. The farmers can use big blocks of land for farming and produce food. You use the land as long as necessary, you can keep it in you family for generations. When there is no one left you give it back to society.
This was the original duty of goverments, but this changed after the private corporations came.
What you see in the documentary is basically the way to do it, but it is really important that people understand what freedom is.
We can't only blaim goverments for our slavery, we have to use our power wisely and work together without fear!
