It also the case that Germany, immediately after WW2, had a regional government imposed on it by the allies. This was to prevent the Capital and one person from becoming too powerful. Consequently, each region has it's own netowrk of govt, hospitals and science companies that it can reach very quickly. There is not the obsession with centralised control evident in the USA and UK. So the constitution imposed by the USA and UK has served Germany well. For the 'winners'? not so much.
