Ok we know the tax bill will add at least $1 trillion to the debt

over the next ten years. I have a question what was the debt already built in to the budget the next 10 years without this so-called tax cut? It had to be already several trillion and what happens when there is a recession. How can we have a tax cut to stimulate the economy when we will already have way over $20 trillion in debt? I think Democrats did a extremely poor job in opposing this bill.
