This plank in Die Partei Bundesverband’s platform is amazing. My non-existent interest in politics is suddenly renewed.

11 Beer price cap

The PARTEI is committed to a nationwide beer price cap and the strengthening of the ordering principle. For this purpose, a beer price index is collected. The brake comes into force as soon as two indicators appear somewhere in the economy at the same time: great thirst and a verifiable empty glass jar rate. In preparation: kebab price brake (3 euros)
