Government Spending at a certain point leads to spending in excess of tax receipts. This will automatically lead to the issue of treasuries in the belief that the excess spending must be financed by borrowing (although the government has the capacity to create money). This in turn will increase the national debt.
Consequences that follow from this practice:
1) That national debt increases whenever the government spends in excess of tax receipts.
2) That the government must pay interest on the debt issued, which in turn increases and reinforces the need for government spending.
3) That the interest paid on treasuries will increase private sector income.
There is an alternative view, supported by Modern Monetary Theory, of how government spending can proceed. Please see this Insight:
