Since then, dependency to corporation tax, tax relief to individual savings, deficiency of taxation consensus, high dependency to debt for governmental finance have been proceed to direction shoup did not want. As a result, tax system based to direct taxation have been maintained to present, especially low burden tax system which allowed various tax exemption and deduction, and depended deficit financing have been developed.
