Granted, I'm not an expert on this, so take what I say with a grain of salt. But, WSJ and CNBC think we need all levers to move the debt, not just one.
Now, there could be an order to this. For example, it probably makes sense to (1) deregulate to promote growth first, (2) then cut spending, (3) then cut interest rates and issue longer term debt to replace shorter term debt, (4) then raise taxes.
Also, there is the 4 year presidential cycle to think about. 1, 2 and 3 could be done under Trump, then do 4 in next presidency. But, Dems may undo 2 and 1 if they win the presidency.
Interestingly, much of this should be the domain of Congress, but Congress doesn't seem to act much even when the majority party matches POTUS...and goes dormant when it doesn't match. POTUS has a lot of power ... so much power that one could consider this a new historical era in the US.
