Why was a more unified Germany seen as a problem or a threat by Metternich? What kind of government in Germany was created instead?

What happened in 1848 in Germany that involved Frederich William IV of Prussia?

i believe the answer is:

at that time, the segment of population that choose for democratic party were the voters with low economic background and vice versa

- william jennings has support of populists and wants to have inflation to farmers while mckinley has support of bankers and businessmen , doesn't want inflation

- william jennings supported the silver standard while mckinley supported the gold standard

according to jenning, using other metal beside gold could the poor people to have more purchasing power and them advance in the society.
