British Agriculture and US

I think one big difference between the UK and the USA is land tenure.  Oversimplifying, to get people to work the land the USA mostly offered ownership, though in the South we used slavery.  In the UK they always had enough people for the land and technology which were available, so they've always had tenants without ownership.  Of course these days the US has lots of renters, but typically outside the South the renter has some owned land, and has expanded her operation by renting from the heirs of deceased owners.  (I don't know how many errors I've written so far.)

To me this difference is shown in the Duke of Westminster, who just died.  The pieces on his death noted he was one of the biggest landowners in the UK, including some 300 acres worth of London.  I don't believe we would see similar stories in the US.  Yes, we've some big owners, like Ted Turner, but their lifestory isn't centered around landowning.

Another big: the Tenant Farmers Association, a UK organization:

  The TFA is the only organisation dedicated to the agricultural tenanted sector and is the authentic voice on behalf of tenant farmers.  The TFA lobbies at all levels of Government and gives professional advice to its members.

The TFA seeks to support and enhance the landlord-tenant system.  It represents and advises members on all aspects of agricultural tenancy and ancillary matters.  It also aims to improve the professional and technical knowledge of its members, to increase the flow of new tenancies onto the market and to help the farming industry best apply existing agricultural tenancy legislation.
