it does not make a difference to those who died and it wond change the fact that hitler would never have come to power with a different economy system.

I disagree, I think he would have come to power anyway. The Nazi party was just the platform he used, they were supposed to be a socialist party, and one of the first things he did when he came to power was to outlaw all Trade Unions, except for the state run "Union", that all employees and employers had to join. The economic state helped, but as Ive said I think his motivation was revenge above all else and he showed his determination through many years of plotting, even a year in prison.
