Summary

This quote suggests that through various means of incentives and punishments, the Austrian population during the Nazi regime was compelled to support and promote the Nazi agenda, similar to a donkey being driven to pull a heavy burden up a hill. The use of "emaciated" highlights the strained and oppressed state of the people, while the image of the donkey symbolizes their forced obedience and labor. The phrase "Nazi barrow" indicates the collective goals and objectives of the Nazi party, which the people were coerced into advancing, regardless of whether they willingly agreed or not.
