Well, lets see…
Hitler increased taxes and government spending, and greatly increased the size of the governments share in the German economy.
He regulated businesses and told them what they could produce, although, he allowed them to continue make profits.
He, along with Porche, personally invented/designed a cheap, reliable, peoples car, that any citizen could afford- the Volkswagan(the most popular car ever in the world, over 50 million sold for over 60 years).
He did massive public projects like inventing freeways(Autobahn).
He invented social security and day care centers, he allowed women to enter the work force.
He was a self made man, rising from poverty, prison, and illigitamcy, to become a world ruler.
He was a best selling author, getting personal wealth from the sale of his books.
The women loved him, at least 4 girlfriends killed themselves on his behalf or because of him, including his cousin.
He ended unemployment in Germany, in the middle of a world wide depression and changed an inflation ravaged poor country into one of the most prosperous and powerful countries in the world.
He greatly improved the national defense.
He was for gun control, and was anti-tobacco, starting the first laws in the western world against smoking in public places, and never allowed smoking in his presence.
He provided government housing, gave free jobs and houses, and businesses to German citizens .
He tried to end racial and ethnic problems in his country. He tried to deport non-Germans to other lands(but no country would take very many of them)
He never nationalized private industry.
He hated war, and tried to end all war with other nations as quickly as possible, getting other countries to surrender before too many people got killed(Russia did not cooperate), and established allowed local native leaders to rule in conquered lands(Denmark, Vichey FRance, etc.)
He was elected, though not a true German citizen and could not legally even vote.
He got massive cooperation from the Soviets, and from American industry and american banks, including loans from George Bush’s father.
He copied the American invention of: “Indian Reservations” and our “Indian policy” of the 1800’s and called them concentration camps.
He started the worlds first “youth program”.
He never invaded Switzerland, he went along with the advice of his generals in leaving Switzerland alone in peace.
On top of all that, he was veggie, a non-smoker, he loved kids and animals, he was a great speaker, and most of his citizens loved him.
What kind of people would vote for someone like that?
(No one, including myself, who firmly believes in the American Bill of Rights, would give this guy the time of day, regardless of that impressive list above )
The answer is, he was both right and left, and people from both the right and left would be attracted and like what he did, and would vote for him.
