That would seem to be the case à la Fisher. But the evidence from Japan, a slowly, albeit steadily, deflating advanced economy is compelling.
From January 1995 to January 2010, Japan's CPI (2005=100) has fallen from 100.8797 to 99.5851, or or -0.08% per year. In that time, real wages grew 0.23% [1]. Real GDP/capita at 0.61%. Hell, from 2010 to 2013 their CPI has fallen at 0.27% annually, but the hit has been mixed. Note that the Japanese monetary base (M2) has expanded at 2.5% annually from 1995 to 2010, so this is a demand-driven deflation, consistent with Morana. But the deflation we base our analysis on, the Great Depression, was similarly spurred by demand.
Similarly, Germany, through the Hartz reforms, engineered a wage deflation at the beginning of this century. Helping power the American recovery is wage deflation. The hope is austerity, structural re-alignment through deflation, will similarly fix peripheral Europe's bloated labour costs.
Yes, it appears people will take falling wages if forced. All this said, I do not believe a deflating national currency is the right model for Bitcoin. Instead, look to arguments levied as the world switched off gold, an international deflationary currency, to inflationary fiat ones.
