Politics and the economy are both looking up. President Obama’s big-government spending, planning, and executive-branch overreach were crushed at the polls. Elections matter. The GOP has been rejuvenated. Republican governors will lead the way. And the Republican majorities in the House and Senate haven’t been this big since the 1920s. They know what to do — develop a positive agenda: Pro-growth tax reform and spending limits. Pro-energy. Pro-King Dollar and Fed monetary reform. Pro-health-care choice. Pro-immigration reform. Pro-marriage. Pro-family.

An American renaissance is in the making. Let the GOP put its best policy foot forward. If President Obama vetoes the growth reforms, so be it. The 2016 agenda will be set for a Republican presidential victory. So why can’t 2015 be an optimistic year? The psychology of pessimism and negativism that has engulfed America for so many years can melt away.

Tom Coburn, who is retiring from the Senate, recently told me that America is a better country than it is showing. I believe we are now poised to show it. Inside the economy, things are looking better. Thanks to the fracking revolution, free-market forces have led to a halving of oil prices, to the enormous benefit of consumers and businesses. While our production cost structure for goods and services has plunged, America has become much more competitive.

Yes, inside the energy sector, there will be displacements. Marginal producers may fall away or consolidate. Extraordinary energy profit margins will normalize. There may even be some debt defaults. Economist Scott Grannis estimates there’s about $180 billion of high-yield energy debt. But only about $30 billion will likely default. That’s a tiny fraction of $5.1 trillion in high-grade corporate debt, an even smaller fraction of $28.3 trillion in U.S. Treasury-, corporate-, and mortgage-debt market value, and a small piece of $23.4 trillion in U.S. equity-market value.

Forget the naysayers. There is no systemic energy banking risk that’s comparable to the 2008 meltdown. Not even remotely. The energy supply shock is unambiguously good.

Lurking behind the energy-price drop (AAA gasoline nationwide is about $2.20, a buck less than a year ago), don’t forget $3 natural gas, which is increasingly gaining energy-market share. Don’t forget the economic destruction falling bomb-like on our oil-producing enemies in Russia, Iran, and Venezuela. The energy fracking revolution has done for national security what President Obama seems incapable of doing.

And don’t forget the economic power of the rising dollar. King Dollar is at an eleven-year high. It’s attracting capital from around the world. It’s holding down inflation. It’s providing major new purchasing power for consumers and businesses. Lower production costs and commodity costs will increase our exports and give us more buying power for the purchase of imports. All this helps the global economic recovery.

Most people have this story wrong. It’s not Europe and Japan that are going to hold the U.S. down. It’s a resurgent U.S. that’s going to build them up — despite all their structural policy mistakes.

Also inside the economy, business investment is improving, housing is slow to recover but is recovering, and wage and salary income is growing at 4.5 percent. Less 2 percent on consumer prices, that leaves over 3 percent of real spending power. Not fabulous, but good.

Looking at Treasury bond yields, real rates are rising — a sign of better growth — while inflation fears are declining. Banking risk indicators, like 2-year swaps spreads, are very low. And profits, the mother’s milk of stocks and the lifeblood of the economy, stand at a record-high share of GDP and are likely to keep growing in a range between 5% and 10%.

Fortunately, the Fed’s QE balance-sheet expansion never really worked. Excess bank reserves never circulated throughout the economy. The money supply has been quiescent. And that’s a good thing, because if QE had worked, the inflation rate could be 10% or 15% percent instead of less than 2%.

Meanwhile, the federal government’s spending size has dropped to less than 21% of GDP from near 25% of GDP. Obama’s so-called spending stimulus has been stood on its head. In the early years more spending generated less growth — the worst recovery since WWII. But in recent times less spending is producing more growth — probably toward a 3% trend. (We need roughly 4% to 5% growth in the years ahead to reclaim America’s 70-year average of 3.5%.)

A final optimistic thought: A big tax cut for large and small businesses combined with King Dollar is the exact supply-side-growth mix that generated booms in the 1960s, ’80s, and ’90s. We can do this.

Happy New Year.
