David Stockman is in the Slough of Despond. Writing in this weekend’s New York Times, Ronald Reagan’s former budget chief argued that it was Sundown in America:

So the Main Street economy is failing while Washington is piling a soaring debt burden on our descendants, unable to rein in either the warfare state or the welfare state or raise the taxes needed to pay the nation’s bills. By default, the Fed has resorted to a radical, uncharted spree of money printing. But the flood of liquidity, instead of spurring banks to lend and corporations to spend, has stayed trapped in the canyons of Wall Street, where it is inflating yet another unsustainable bubble.

When it bursts, there will be no new round of bailouts like the ones the banks got in 2008. Instead, America will descend into an era of zero-sum austerity and virulent political conflict, extinguishing even today’s feeble remnants of economic growth.

Stockman has no praise for Ben Bernanke. But he has even less for his former political party. The Republicans, under his former boss, became Keynesians:

The destruction of fiscal rectitude under Ronald Reagan — one reason I resigned as his budget chief in 1985 — was the greatest of his many dramatic acts. It created a template for the Republicans’ utter abandonment of the balanced-budget policies of Calvin Coolidge and allowed George W. Bush to dive into the deep end, bankrupting the nation through two misbegotten and unfinanced wars, a giant expansion of Medicare and a tax-cutting spree for the wealthy that turned K Street lobbyists into the de facto office of national tax policy. In effect, the G.O.P. embraced Keynesianism — for the wealthy.

The explosion of the housing market, abetted by phony credit ratings, securitization shenanigans and willful malpractice by mortgage lenders, originators and brokers, has been well documented. Less known is the balance-sheet explosion among the top 10 Wall Street banks during the eight years ending in 2008. Though their tiny sliver of equity capital hardly grew, their dependence on unstable “hot money” soared as the regulatory harness the Glass-Steagall Act had wisely imposed during the Depression was totally dismantled.

I would argue that Stockman profoundly misreads Keynes. For him, deficits did matter. But the time to deal with them was the time of milk and honey. The problem was — and is — that, despite their caterwauling about debt, deficits never mattered to Republicans.

The result, Stockman writes, is a very bleak future:

The greatest construction boom in recorded history — China’s money dump on infrastructure over the last 15 years — is slowing. Brazil, India, Russia, Turkey, South Africa and all the other growing middle-income nations cannot make up for the shortfall in demand. The American machinery of monetary and fiscal stimulus has reached its limits. Japan is sinking into old-age bankruptcy and Europe into welfare-state senescence. The new rulers enthroned in Beijing last year know that after two decades of wild lending, speculation and building, even they will face a day of reckoning, too.

There are dark days ahead. Whether or not the United States will solve its fiscal problems is an open question However, I’m not convinced that America necessarily faces Financial Armageddon. It does seem, though, that Stockman faces a Dark Night of the Soul.
