I believe that this idiotic short-sighted minmaxing (mainly due to the conservative party) has led to many of Germany's current infrastructure issues. Laying fiber? VDSL is cheap and has been good enough so far. Renewable energies? Importing Russian gas halves CO2 emissions compared to coal and is way cheaper (surely Russia would never think of abusing the dependence). Maintaining the railway network? That would cost money, and it wasn't broken yet.
