That's for sure. But Germany at the moment is in a phase where the decentralization is biting it. While UK seems to succeed in some areas where Germany fails at the moment. So it's fascinating to see such a comment.
There are lots of tradeoffs with the current decentral/federated system for sure. But one key point is that it’s incredibly hard for an extremist or fascist party to take over the whole country and run it into the ground quickly(again!). And with the growing rightwing populism over here it’s a good thing to prevent the worst.
Of course the setup also slows down progressive policies or any changes in general due to conservatives/rightwingers blocking things, but that’s the price of it.
