Affordability of a basic income proposal is a function of the social/government services it replaces, any tax increases, and the less tangible positive effects on spending and tax receipts associated with wealth redistribution towards the poor, and any social savings as a result of less crime, or fewer incarcerable offenses.
Specific, though informal, measurements were made by Pascal J. for Canada.[123] A 2004 taxable basic income benefit of $7800 per adult could be afforded without any tax increases by replacing welfare, unemployment, and core Old age services. (Canada has supplemental poverty old age programs and pension system). The number excludes any intangible benefits of tax revenue increases due to higher spending and lower personal savings, and any expenditure savings on criminal enforcement.
