Corky has put his finger on something fundamental, In that there are profound differences between the retailer's mentality and that of the poducer. This may be simply explained when one realises that the retailer has to maximise variety and options, whereas the producer needs to reduce variety and standardise methods and products.
There are therefore two conflicting points of view, and these are normally reconciled through the market mechanism. Unfortunately, that mechanism is now weighted heavily in favour of the retailer, and this is because Politicians have let the market become unbalanced.
Instead of preventing the growth of monopolies (or oligopolies) politicians allowed, and possibly encouraged the increased power of the retail sector. A consequence of this inbalance is that retailers can now scour the world for products with a buying power based on their assured home customer base. On the other hand, the producer has not got a substantial home sales platform and therefore, cannot gear up to compete for foreign sales, or indeed home sales, even assuming he has what they need.
The UK producer has therefore, neither capital capacity nor systems to negotiate with the UK or foreign retail sector on an equal basis. Producers are very reliant on retailer good will, and a, 'if I touch my forelock Mr Tesco, will you please consider buying my product' approach.
A level playing field, based on equal powers in the hands of the retailing and producing sectors must be established by our political parties. It is clear after nearly eleven years that the Labour Party will not provide this because it is in thrall to the Retail Sector, and has an emotional and irrational antipathy to country folk.
Whether the Tories will, I know not.
