How did marx & engles turn the world upside down with their views?

We can consider some of their ideas that still being followed and supported by many, some of them are:

1. To extinguish the property on the land and use of all the income obtained with the lands in the expenses of the State.

2. Highly rising income tax.

3. Extinguishing all inheritance rights.

4. Confiscation of the property of all emigrants and rebels.

5. Centralization of credit in the hands of the State, through a national bank with state capital using exclusive monopoly.

6. Centralization, in the hands of the State, of all means of communication and transportation. Nothing out of state!

7. Expansion of factories and production instruments belonging to the State; the clearing of uncultivated land and the improvement of cultivated land, all according to a general plan drawn up by the State.

8. Everyone should have an obligation to work. Creation of industrial armies, especially for agriculture.

9. Unification of agricultural and industrial labor. Gradual abolition of any distinction between town and country by means of a balanced distribution of population throughout the territory of the country.

10. Free education for all children in public schools. Elimination of child labor in factories in its current form (at that time). Unification of education with industrial production, etc.

world war i had a devastating effect on german-americans and their cultural heritage. up until that point   german-americans, as a group, had been spared much of the discrimination, abuse, rejection, collective mistrust experienced by so many different racial and ethnic groups in the history of the united states. indeed, over the years, they had been viewed as a well integrated and esteemed part of american society. all of this change with the outbreak of war.  

you should think about the answers you give and expect the same form your questions.
