I agree, but the SPD went through with it. The two largest parties in Germany aren't interested in bettering the country they're interested in making press headlines while increasing the wealth of their friends and the wealthy.
The fact that the first three policies I've seen come out of this coalition are increasing our national debt, wanting to decrease taxes on the wealthy, and removing a niche path to citizenship for the people we want here the most should be a wake up call for the - what 40% of Germans who voted for these people. They're antiquated parties incapable of making real progress for the working German.
The only way to address the AfD is to tax the rich, deal with wealth inequality, improve the lives of the working German, and root out corruption and oligarchy at every level.
The CDU and the SPD allow the AfD to thrive because one of them encourages and cultivates the climate that leads to the AfD and the other refuses to make significant enough changes to reverse the damage conservatives do to a country.
