Communism

I thought the bourgeoisie state created the tools of its own demise!

The bourgeoise will indeed make their own downfall. They will gladly sell us the rope used to hang them with. The laws, the working of capitalism will deteriorate conditions for the proletariat readying them to do that hanging.

But the bourgeois will not hang themselves. And without work, the downfall will not happen.
A fallow field will not make food, it will create dirt more ripe for it, through the laws, the working of nature. But we must sow the seeds, and watch them, potentially spray them with pesticide, and finally harvest them.
