Here it was in 2006, at the Berlin Air Show:
I know your statement was a rhetorical tool...:)
One of the major problems faced by Germany was the nature of its industrial processes.
Sure, they had mass production, but their mass production was different in a key way from American mass production.
Using the industrial mass production principles of Henry Ford, American industry was able to make parts with a uniform tolerance that made interchangability of parts a reality. You could take a manifold off a radial engine on a B-24 and bolt it onto another B-24 that whose manifold needed replacing.
The Germans produced fine machinery, but they were largely using craftsman techniques to construct them, where individual parts could not always be taken from one device and used interchangeably on another with a degree of modification, filing, hammering, drilling, etc. (I heard it characterized as making custom timepieces on a grand scale)
A good example of this is the German tank industry. Their tanks are widely regarded as having been superior machines in most respects, but one area they were far less capable was maintainability. When their tanks needed maintenance and repair, it took longer to perform the actual maintenance and repair simply because cannibalizing a piece of equipment off of one tank was not a slam dunk that it would fit in the same type of machine without a degree of modification.
And this subtle difference was apparently endemic to many of the pieces of warfighting equipment they used.
Add onto that the fact they used slave labor in many areas, which decreased the quality even further, intentionally in some respects.
This is contrasted with the American policy of largely allowing the capitalist mechanisms to take effect, primarily the profit motive. FDR resisted mightily the impulse to allow this, but he was convinced by William Knudsen (who learned his mass production techniques largely from Henry Ford, and refined them into what we have today) that to achieve the production goals as we led up to, and entered WWII, we had to allow the manufacturers of war materials to make money doing it. FDR opposed this on many levels, but to his credit, he eventually agreed to the howls of protest from his New Deal disciples.
Germany had no such discussion or understanding of these things.
They delayed the introduction enough to make the 262's contribution the War minimal.
If it had been introduced in say, 1943, then the air war in Europe is a different game.
The Allies would did have jet technology....not as advanced as the Germans.
The Allies philosophy in the War was to bury the Axis powers through production. The amount of war material we produced was staggering.
When you're in the position of the Germans it forces you to think a bit differently.
