i'm wendy edelberg from the congressional budget office. let me give you a quick summary of what i'll say. i'll briefly walk you through cbo's budget and economic projections and highlight some of the significant consequences we see from our projections of high-end rising federal debt. and how the economic projections influence our budgetary projections and the interplay of those two. finally, i'll talk about automatic stabilizers. role of automatic stabilizers and fiscal policy during times of economic weakness. all right. i'll skip that one. this might look familiar. david just showed it. so, under current law, revenues are projected to stay roughly constant as a share of gdp over the next decade. but with the aging of the population and rising health care costs, cbo projects a substantial boost of federal spending on social security and the government's major health care programs. so, alongside rising federal interest payments, deficits are expected to increase from their current level of 2.9%, a touch higher from the average of 2.8% ove
