To what extent were economic factors the main reason for the rise to power of a ruler of a single party state?

Economic factors contributed significantly to the rise to power of Hitler in Nazi Germany. The Wall Street Crash of 1929 led to economic depression in Germany which caused people to lose trust in the current Weimar government and turn instead to extremist parties. This can be seen as the Nazis only won 12 seats in the Reichstag in 1928 compared to 230 seats in the 1933 elections. This significant increase shows that their popularity has increased. Moreover, this increase in popularity was partly due to the promises they made to various social groups, such as increased prices for farmer's produce. The suffering because of economic difficulty, such as unemployment reaching 6 million in 1933 caused people to vote for extremist parties such as the Nazis.
