France has a crushing, monolithic bureaucracy and is unable to modernise or avoid stonewalling factions from unions to farmers. They are big and powerful enough to get away with it. Witness the current issue they have with retirement age. Currently it is 62. They really should up that as people live and can be productive so much longer and the population is aging with a higher proportion of aged people. However the unions simply will not allow it. If the duly elected government attempts to do this, the unions will simply shut the country down. Farmers likewise, will prevent any modernisation of their protected agricultural sector.
Germany seems to be a bit more sane than most, but look at their self inflicted renewable energy conundrum - finding themselves dependent on Russian oil and gas for crying out loud.
OK, but what does that have or not have to do with their presidential system?
