A radical improvement in the national debt at the hands of the world's most competent entrepeneur? I think many people were voting specifically for this. Things are going exactly as advertised.
You are conflating debt and deficit. Cutting the deficit by a few hundred billion dollars will barely impact the rate of growth of the debt, it's not a "radical improvement in the national debt", it's a modest reduction in spending.
That seems somewhat inverted - the elected government is creating checks and balances on unelected bureaucrats.
