One of the factors that make German products more expensive is ancillary 
labour costs.

Employers in Germany must pay almost 40% on top of the actual 
wages/salaries in contributions to health insurance, pensions, 
unemployment insurance etc.

The figure for Japan is around 25%.

On the subject of glass:

Leica now buys in a lot of their special glasses from Asian 
manufacturers like Hoya (Tokina) and Ohara (who supply glass to just 
about everyone). Here's their list of customers in Europe:

AFAIK, grinding and polishing is no longer so much of a cost factor at 
Leica. For example, the asphericals are now pressed in a special process 
developed in Solms.

What must be a large cost factor at Leica is their quality assurance 
philosophy - only the tightest tolerances are good enough - this must 
lead to enormous numbers of rejects, particularly in the case of lens 
elements.  When I last took a factory tour, they came around with a tray 
piled high with rejects for us to take home as souvenirs.
