(Think you meant something else than Ju 88, in your post, btw!

)
Fair comment, but you can argue the other way just as well - the most famous example being the Sherman tank vs the better German examples.
Not many people realise one reason for the development of the Ju 87 Stuka was the Luftwaffe could have a lot more of them
and they were more effective tactically than a conventional twin-engine bomber or a mutli-role type like the Ju 88. The Germans switched to a tactical air force with the death of General Wever (
not only because of bang-for-buck, btw) and the advocacy of dive bombers by Udet, and integrated that into the Blizkrieg. Had they been able to develop a strategic bomber arm either instead of (possible) or as well (financially and production terms impossible) they'd actually have done a lot worse in their early war battles than they did. Heaver conventional bombers (of the pre-1940 designs) would've been worse at the jobs that the Luftwaffe's twin-engine bombers and particularly the Stuka. Yes, the Battle of Britain would've been won
earlier at
less cost to Britain, and the effect of the May 1940 Blitz and the battles of the Med would've been a less 'close run thing'.
One of the tricks is
what are the lessons of history? I'd agree with your bomber comparisons, but...
Certainly military equipment isn't getting cheaper, but the US has been using over-sophisticated bombers for less sophisticated tasks since Vietnam. Some (how much and what is an arguable and variable question) of that sophistication has been unused or unrequired in each war fought; had the crystal ball gazers been able to channel that equipment cost more usefully, that would be more munition on target. But that's easy hindsight, of course.
