Since 1949, job growth under Democratic presidencies has been more than twice as large as that during Republican administrations (2.47% to 1.07%). Excluding public sector jobs, the advantage is even greater (2.55% to 0.97%). Other key averages reveal a similar distinction during this period: Real business investment growth advanced 6.58% under Democratic presidents and 2.98% under their Republican counterparts; real personal income — excluding government transfers — increased 2.66% and real economic growth per capita (net domestic product) advanced 2.6% under Democratic chief executives, but only by 1.41% and 1.28%, respectively, under Republican leaders. Inflation has also been much more modest under Democratic presidents (2.91% compared to 3.28% under their Republican counterparts), with an even more decided advantage when volatile energy and food markets are excluded (2.87% compared to 3.59%).

Of the 11 U.S. recessions we’ve endured over the past 75 years, 10 began in Republican presidential administrations; only Jimmy Carter — embracing Republican-style fiscal, monetary and regulatory policy much more completely than any other recent Democratic president — presided over a “Democratic” recession. The two “double-dip” recessions of 1980 and 1981-82, straddling the late Carter and early Reagan administrations, are almost indistinguishable in their policy origins.

We are reminded consistently by pundits, journalists and scholars that tax cuts represent what may be our most readily available and useful tool for economic stimulus. Flat, or flatter, taxes, we are told, are the only means to the achievement of tax simplicity and tax compliance.

Even on the question of who tends to favor lower or higher taxes, it is easy to be deceived. When income taxes are reduced (at the federal and state level) and the entire tax code is rendered less progressive as a result, two things happen almost automatically: other much more regressive taxes rise to fill the vacuum created by universally demanded (if not readily acknowledged) public services and consumer demand falters as higher taxes begin to fall on those compelled to spend all that they earn. Overall economic activity and prospective revenue growth, in turn, begin to stagnate, triggering a vicious cycle of tax rate increases (among the untouched regressive tax vehicles), just to maintain public services and economic activity.

Republican politicians have stumbled upon a remarkably effective political strategy: preach tax cuts as the be-all and end-all of successful economic policy; ignore the ways in which federal income tax cuts often lead to increased tolls, fees and property, sales, and excise tax increases; relinquish all but rhetorical opposition to the federal deficits created by federal tax cuts; and cap it off by hinting repeatedly that more could be done — allegedly to great effect — by reducing government spending directed at “undeserving” and “unambitious” poor people of color.

Republican political leaders have their cake and eat it too, riding a diffuse anti-tax sentiment to political victory. Actual results in this game don’t often matter, at least as long as their Democratic opponents succeed in staving off the most precipitous decline with safety nets and the preservation of some progressive fiscal policy elements.

Begun quietly with what Republican activist and Wall Street Journal editor Jude Wanniski called the “Two Santa Claus Theory” — under which Republicans could counter the Democratic social spending Santa Claus with their own tax-cutting Kris Kringle — this approach promised political “success” even amid policy failure, for opponents could be pinned with the deficits and damage it produced.

Exploiting normal psychological tendencies to imagine that “more money in my pocket” and “less money in theirs” simply must be good policy, the widespread ignorance of actual public spending and significant intergovernmental fiscal policies (where federal change forces state and local change, or vice versa), and the compelling notion that personal economic opportunity or success must be derived from personal talent and initiative (rather than significant public policy reform), the “Two Santa Claus” strategy has buoyed a Republican Party that has consistently delivered sub-par results.
