U bet he did!
At the time Hitler took over the reigns of Germany, it was a war ravaged and heavily indebted country with the economy in absolute mess. He was instrumental in turning around his country and converting it into a world power of his times.
And then crushing it into the ground with a war that would last half a decade and see great swathes of the county destroyed, killing hundreds of thousands of civilians in the process. It was the allieds who supplied the funds, equipment and manpower to rebuild after the war. In addition a lot of these economic advances we're made by grabbing the resources of the countries around him.
He was instrumental in putting in place most of the infrastructure in Germany, much of it in use till today:
1. he built the autobahn
No, he didn't. He built some of the first foundations of the highway network to support the war movement.
2. he built the vw beetle.
Again, no he didn't. Unless he somehow time traveled to the sixties to design it.
3. he built the berlin olympic stadium
Huzzah! A giant pointless structure built whilst the citizens of Germany were still struggling!
4. he invested heavily in german infrastructure
In order to take over all of Europe. What a nice guy!
5. he made the 1st practical rockets and cruise missiles.
With which to drop bombs on London, killing civilians at random. Wow!
6. made the 1st jet plane.
With which to shoot down allied pilots trying to stop his aforementioned wanton murder.
7. Great Advances in trauma therapy were made.
By killing millions of people and observing how they died in horrific circumstances! FANTASTIC!
Kind things:
8. cancelled 'operation sea lion', the expedition to England- as it would result in huge loss of civilian lives
Replace huge loss of civilian lives with "Would have lost the war as he was alread fighting on two fronts, then yes! Just for the record of all the answers so far this has been the most retarded.
9. Let the Battle hardened Allied troops(about 1million) escape Dunkirk on humanitarian considerations-could have crushed them all
No, he couldn't of. Infact the troops fought all the way to the evacuation points against fierce resistance.
10. The nuclear bomb technology was developed by German scientists in his regime(mostly same people migrated to USA and created the Bombs that USA used on Hiroshima & Nagasaki- AFTER the war was OVER!!!!!!)- but could not bring himself to use them on humanitarian considerations. (And he is blamed by American and English media of atrocities on humanity!!!!)
The fact that Germany never made a nuclear bomb, and infact lost the war way before it's bomb project came anywhere near making one, may have also been a contributing factor.
As to how the American's developed the nuclear bomb, that would be the years spent on the manhattan project, not stealing it from the Germans. On a side note, some German scientists were offered jobs in America to work on rocket projects after the war.
11. A great fall out of WW II brought about by him- England/Britain, France, etc had to cede/liberate most colonies in Asia, Africa, etal.
Thus bringing to an end the severe oppression and violation of human rights by the occupiers in these countries.
Which I'm sure he intended all along! Also, the war had nothing to do with this.
No doubt, great atrocities were brought upon the Jews in his regime. Weren't Jews persecuted in rest of Europe?
Can't remember any other countries attempting to wipe them from the face of the earth at that period in time. 
However, consider the atrocities in occupied territories(colonies) perpetrated by other Europeans - native Americans were looted & hunted down like animals; Aborigines and Maoris of Australia and New Zealand suffered similar fate. Asians, particularly Indians were subjected to the darkest forms of treachery, cruelity, atrocities, injustice.........etc; Africans were killed, enslaved and raped at random!! N-bombs dropped in Japan AFTER the war was OVER!!!! The atrocities, open murder and rape of people in Korea,Vietnam and now Iraq!!!!!
Yeah, except that that never happened. And of course when native's were treated badly by other countries it usually wasn't for the purposes of killing them all. Also, Hitlers troops were way better than troops of other armies, I mean it's not like they raped, murdered, killed and looted at all. Well apart from nearly everyone outside of the German borders, but let's ignore that.
All this by the so-called defenders of humanity!!!!!!
And they say Hitler was bad!!!!!!
Yeah, they do.
Let's not forget that 'HISTORY IS WRITTEN BY THE VICTOR'
