I did two quick and dirty looks at economic statistics this evening.

Conspicuous rise in capital income share (of total national income) after the Schröder administration's "Agenda 2010" reforms (supposedly a social-democratic / green cabinet):

During 2003-2007 capital income rose from 29% to 37%, an unprecedented increase.
The range for capital income % for 1991-2011 was 28 to 37% (now 33%)
The same range was in 1970-1990 in the West Germany only: 26 to 34%

Judging by this quick&dirty calculation, your economy does not justify 70+ % of your goods consumption.
