"Less than 30% of the Budget is Discretionary spending"
True. 2019 budget discretionary is $1.4T of $4.7T or about 29.8%.
Point?
Interest on the national debt is another $0.5T, leaving $2.8T mandatory.
Is the point that we should cut Social Security, Medicare and Medicaid (Half of which is long-term care of the elderly)? Those 3 programs cost $2.2T of the $2.8T mandatory budget.
Or do you want to eliminate tax credits like EITC and Child Tax Credit? Those are $120B. Why are tax credits to the poor and middle class counted as spending, instead of just reductions to net revenue? Capital loss tax credits aren't accounted as spending.
Or do you think we should cut pensions for retired military and other government workers?
I'd love for Republicans to run on that platform.
The stuff Republicans like to focus on cutting, like food stamps ($68B), TANF ($17B) and section 8 housing ($30B; which I personally would love to see eliminated) amount to less than 3% of the budget.
