Since we are all friends here, I am going to explain how I make money. Since we don't even live in the same country, I don't fear competition. Also, it is easier here to do this.
I don't like middlemen, they take a percentage with very little risk, and very little outlay of capital. So, I won't grow anything or
sell anything if I don't own the whole chain. For example, we make furniture, but we have nursery, plantations, sawmills, mills, and furniture factory and sell to the end customer. All the
profit only goes to two owners, my wife and I.
Now I am getting into sheep, organic produce and fish. Before we really produce, I will create a store which is part butcher shop, part vegetable stand. The supermarkets are not going to be happy with me because I am going to undercut them with better quality and organic. I already have customers lining up... Again, simple for me to do since we have it all.
I also constantly am looking for "waste". Waste from the sawmills in the form of sawdust gets used as bedding for nearly 80 sheep (flock has been growing!), after one week, this bedding is dirty and gets dumped on the organic garden. Butchered (and dead of natural causes) sheep entrails
feed the catfish and langostinos. Whereever there is waste, there is an opportunity for profit.
Since we run so efficiently, there is money for the next big thing we do. And since everything just gets better and better, we don't really worry too much about the system breaking down.
It is very hard to compete with someone with a vertical monopoly because there is only person taking out profit, and the taxman only gets to grab a cut at the very end.
We use our advantage to be able to do a better job, and pay people with more benefits. This insures we keep the best workers possible.
Permaculture works I believe when it is used as a method of taking the long view, and that is about efficiency and not wasting anything.
