I think Prof Ruttner summed it up very well when he differentiated between the economic value of a queen and the breeding value. The economic value is limited to the financial value of the products of her colony (honey sales, wax, etc) but the breeding value is much greater. For example, a pedigree racehorse might run in a number of races. It might even win some prize money - it is through this performance that its breeding value is judged. When the racehorse retires it may go out to stud, producing offspring that have far greater value because of how they can reasonably be expected to perform (based on the performance of their parents).
"The average beekeeper" is looking for economic value. Nothing more. The breeder has the knowledge and skill to bring together the dam and sire so that the offspring has the highest breeding value.
I agree it is well enough summarised. I understand zuchtwerte/breeding value and it is translated into, used to accentuate, various traits be that longevity, hygienic behaviour, nectar collection and so on – ultimately that becomes of economic value through the 'improved' specific behaviours. e.g. gentleness, non swarmy etc etc. The beekeeper however is required in this process in order to validate the breeding values. Hence the need for active participation and feedback.
