Germany is in structural decline & the path for that was waved by Angela Merkel who:
a) Allowed for mass irregular migration since 2015 that paved ways for Brexit, the far right rise in Germany and Europe
b) Appeasing Russia after its annexation of Crimea and expansion dependency on Russian gas
c) Phasing out nuclear energy.
As a result, Germany today deals with HIGHER input costs (energy is obvs) & also the political fallout of irregular migration.
Sholz of course is a worse politician than Angela Merkel but the path of its demise is paved by her.
