This past bill isn't the end. Now whether Pelosi initiates it or McConnell initiates it there will be another $2 trillion or $3 trillion or $4 trillion bill that will be passed. Then you have Trump's infrastructure bill for another $2 trillion and you'll have lost revenue to boot. An $8 trillion deficit for 2020 is not out of the question.
Couple that with the fact that hundreds of billions if not trillions of dollars are not flowing into The Treasury to begin with and that debt will be even larger.
