Even here in Canada with regulation we see the same consolidation happening. The quotas of production have become so expensive that it is not possible to start from scratch. In the case of my familly the cows were sold in 1989 because it was either growing the farm or selling.

Now we produce only corn & soybean and despiste our ~100 acres it is not enough to sustain one person without a side job. There is not much money to be made in agriculture for small farms, that's why I am a software engineer.
