As Canadians workers’ wages and salaries declined as a share of GDP between 1990 and 2008, so did  consumption as a share of GDP over the same period.

The interesting part is on the business side. Over the same period, the federal corporate income tax (CIT) rate was cut from 28.84% to 19.5% (Excel file).  The result: business capital investment increased by 0.6% as a share of GDP, whereas corporate profits increased by 7.3% as a share of GDP between 1990 and 2008.
