No, Germany was closer in industrial production than even UK/France than the CSA was to the USA.
Plus, unlike the CSA, the Germans had better parity in numbers. What fucked them was their armor and air power. The former had some good advantages, but the fact is sending training tanks and early run semi-prototypes against a more proven design does not work well. Their tactics were good, but the French were not stupid and they adapted quickly, something planners didn't factor in readily. The repeated hiccups of their engines didn't help. Airpower wise, they picked poorly too; especially for bomber frames.
There is the core of it. Lacking a heavy artillery echelon, and being short ammunition compared to the French the Germans went for a doctrine of out tempoing the Allied armies. While they did do that vs Poland, and in taking Norway, and in the opening weeks in the west, they were not able to sustain the tempo long enough to get out from under Allied fire power. Maybe if they had better developed their air force as a tactical strike force to substitute for the missing artillery? They did try but did not bring the techniques to the necessary level. Nothing close to the level the Americans used against the Japanese in the Pacific war. German morale really suffered when casualties hit 120,000 dead in the ninth week of the campaign. Nothing compared to Verdun, but then the German army of 1940 was a much more brittle sword.
They tried that to a degree; the shittastic Junkers Ju87, nicknamed the Stuka, also nicknamed the Sarg, or Coffin. It allowed for great and accurate bombing due to its dive profile, but it could knock you out with G-forces if you go in too fast, the climb was terrible (meaning if you dived too low... blam), and it was slow and easily shot down. Good against the Polish, who were just starting to modernize their air force, a terrible joke against the Belgians and especially the French. An Me109 variant would do well at the job to some degree I'd reckon; their 20mm cannons were pretty nasty, but the Germans needed a better bomber frame and design for sure.
And focusing Krupp to produce those Marders was not a wise decision, I will agree they needed more basic Arty. Simple is better, which is why Stalin managed to basically roll right in with what he had. I guess it isn't smart to write a book about how you want to destroy the Soviets as policy when the leader at the time was a paranoid and ruthless man, eh?
