I think subsidies could help buying the technology, taking them out would be disastrous.

Farms, at least in Europe, are in the majority family owned. Same for those working in them, mostly those that are part of the family [1].

It's difficult being a farmer. You are much more at the will of nature than any other industry. Your effort takes a long time to bear fruit (think olives, for example, you do not have fruit for 4~years if you're lucky, and you don't want the oil from a younger tree (lesser phenols, etc...). You have to wait YEARS before you get anything to market. And, there have been many fires in southern Europe...).

All in all, it's indeed difficult to invest in machinery, new technology, etc...
