I believe the approximate budget numbers I have seen are that we are on track to spend 7 trillion dollars yearly and going up, while taking in only 5 trillion. We must necessarily borrow the extra 2 trillion somehow, or print it out of thin air, and service the ever growing interest on existing national debt, which also grows by that 2 trillion every year. Elon is correct, this is not and never has been sustainable. We must demand change by our elected officials and now it is emergency action only that will help in time.
The problem is spending and not on food stamps - sure there are a few abusers but every government program and agency has them. Cutting waste and fraud seems to be in, but a lot of those cuts are to useful and needful people as well as programs.
Take back all the green new deal money, contracts and stop subsidizing wind solar and bio power - that alone would be a trillion or more saved
