Not as much money to make, influential people to influence in Spain as in the UK.
It's 50% a hobby/actual interest
50% business + politics
The latter part is nonexistent or not worth it or rather useless in Spain which is a nice holiday country, but don't exert much influence nor have major corporations, banks and others with HQs located there.
Germany is the 4th largest economy in the world, i doubt they have issues with lack of major corporations.
Its still a one-horse league though, maybe because 50+1 rule?
