We forgot one important thing when we did the cost comparison of German tanks vs. Sherman or T34. That is the cost and the resources spend for the development of the systems.

There are lot systems that are very complex and then only built in a very small number, like the Ferdinand "Elefant".

Similar things at the Luftwaffe were you do not only have the Me262 as an advanced fighter but also planes like the Komet or the Volksjäger.

These 'high technology' programs seem to me like a waste of capacities. This may be one reason why some important new systems (like the Me262) came only in small numbers and too late.
