There also seems to be a value dissonance. I like my regional public bank and my regional/local saving bank. I think the are a valuable part of the German banking system and should be defended against the ravaging neoliberalism. As should be the equivalent parts of the banking system of other European countries. (And the state bank of North Dakota)

And you do discriminate against other Europeans:

Domestic need-to-save
Foreign need-to-save
Domestic want-to-save
Foreign want-to-save

A clear hierarchy of needs against foreigners.
