When the redistributive elements in tax systems were weakened, thereby reinforcing the tendency towards greater inequality, the increase in the share of capital in GDP was not accompanied by the expected rise of fixed investment. Such a view fails to consider the benefits for the economy as a whole from a more equitable distribution of income and wealth resulting from fiscal measures - both on the revenue and expenditure side. First, there is a social return for taxpayers, even though it may not be proportional to each income group’s tax burden. Government expenditure, no matter how this is financed, has direct effects on income.
