President Trump on Monday sent Congress a $4.4 trillion budget with steep cuts in domestic programs and entitlements, including Medicare, and large increases for the military, envisioning deficits totaling at least $7.1 trillion over the next decade. The blueprint, which has little to no chance of being enacted as written, amounts to a vision statement by Mr. Trump, whose plan discards longtime  Republican orthodoxy about balancing the budget, instead embracing last year’s $1.5 trillion tax cut and new spending on a major infrastructure initiative.

Left-leaning economists hate the timing and the composition. But the expansionary fiscal policy they sought is on the way. The fiscal austerity that drove the budget deficit from around 9 percent of G.D.P. in 2010 to 3 percent in 2016 has, for practical purposes, been abandoned. First, Republicans passed a $1.5 trillion tax bill in December that sharply cut rates on businesses. Then last week they made a deal to undo budget caps demanded by the Republican House in 2011. President Trump signed that bill on Friday.

President Trump’s proposal on Thursday for deep cuts to the budgets of a broad part of the federal bureaucracy was billed as a tough-minded and necessary corrective to the growth of the government’s power. But even  members of his own party questioned some of the cuts — and what was not being cut. “While we have a responsibility to reduce our federal deficit, I am disappointed that many of the reductions and eliminations proposed in the president’s skinny budget are draconian, careless and counterproductive,” said Representative Harold Rogers, Republican of Kentucky and a former chairman of the House Appropriations Committee.

In a stunning move, the Republican-led U.S. Senate has just passed a  concurrent budget resolution that will increase the federal debt by a whopping 10 trillion dollars. Under the questionable leadership of Senate Majority Leader Mitch McConnell, the Senate voted to authorize a national debt of over $29 trillion over the next years.
