As to the discussion of family farm succession to the next generation. It isn't just that the next gen never wants to farm. Part of the problem is that you can have too many successors and the split becomes problematic if not planned very well, and planned way in advance. For example, on one multi-generational farm of which I am familiar, the farm was started around 1900. When 1st gen passed away, it went to his two sons and part ownership to a daughter that was not involved in the operation of the business. So 2nd gen was a three way split. That works, the farm grew and there was enough income. The 2nd gen folks each had 3 kids. As it passes to the 3rd gen, some of the folks wanted to farm, some just wanted some ownership, and some wanted to cash out. You have 9 successors, but it's not all neat a tidy as not all the 2nd gen want to pass on the farm (or die) at the same time. Now we go to the next gen, and the potential ownership of the farm can be a couple dozen families. Combine that with some really stout land prices and sometimes selling the farm means everyone is well off.
Family owned business succession through the generations is complicated. It takes a pretty tight family with some smart pre-planning to make it happen. It's not always a lack of desire or "those darn kids running off to the city and don't want to work" type of deal.
