As we come up on President Trump’s first anniversary in office, we can look back on a year that has been tremendous for the US economy.

Much to the chagrin of virtually every Democrat — and probably half of the Republicans — Trump has completely changed the landscape of the economy, and many Americans have enjoyed the fruits of higher wages and more robust retirement funds.

For starters, the president’s work ethic is contagious. The guy went to work for the American worker right after the election, well before being sworn in as president.

He jumped into negotiating with Carrier in order to keep Indiana-based factory jobs from moving to Mexico. And while it was a small victory, the statement was very big.

Trump’s action showed that no job is too small to fight for and save. And that was not lost on the middle-class workers of America. There wasn’t a factory worker or middle-management type who couldn’t identify with the jobs he saved right before Christmas. Remember, Trump wasn’t even president yet.

I love economics because it’s math, and there’s no BS in math.

Just look at the gross domestic product. President Trump’s first full quarter in office was Q2, which notched 3.1 percent growth. And for Q3, despite the two hurricanes in succession, he posted 3.0 percent growth.

Better still, the Atlanta Federal Reserve’s GDPNow — the most accurate live predictor of economic growth — had Q4 pegged at 4.5 percent growth, which it lowered it to 3.3 percent after October’s jobs report on Friday.

It’s a welcome reprieve from the eight years of President Obama’s miserable 1.6 percent average, and an unmatched achievement by any other president in our history.

Trump’s three quarters of 3 percent and up GDP growth cements the shifts toward the American economy and the American worker’s mindset.

Unemployment under Trump plummeted to 4.1 percent as of October’s jobs report, released on Friday. That is a 16-year low.

Under Obama, through Fed chair Janet Yellen’s zero-interest-rate policy, it hovered at around 4.9 percent.

And most of the jobs created under Obama’s false employment economy were “gig jobs,” or part-time employment with few to no benefits — 10 hours here, 14 hours there, six hours there.

Today, at more than three-quarters of a point improvement in unemployment, wages have begun to rise.

In the third quarter, wages grew 0.7 percent, up from 0.5 percent in the second quarter. Wage growth, which is the byproduct of corporate profit growth and tighter employment, is finally making its way to the paycheck. But there’s plenty of catch-up needed to make up for the unprosperous past eight years.

It should come as no surprise that consumer confidence is skyrocketing, hitting 125.9 in October — that’s the highest level since December 2000.

Sentiment among small businesses — which employ about 50 percent of the workforce and lead job creation — has surged from the low-to-mid-90s pre-election to 103 in September, according to the NFIB Index of Small Business Optimism.

Last week, the president and Congress rolled out their much-anticipated tax plan. And pretty much as expected, it’s solid overall.

There’s not as much relief as I’d like, especially for those in metropolitan areas or suburbs, but maybe the Democrats can pitch in some votes and gain something for their own constituents.

Finally, the true growth of the economy is manifested in the stock market. The endorsement of Trump’s policies is reflected in the Dow Jones — which is up 29 percent since the election.

This meteoric rise in stocks reflects Trump’s implementation of pro-growth policies and regulatory rollbacks through executive orders, which restarted the US pro-business heartbeat.

While Trump is probably the most politically incorrect president we have ever had, he’s brutally honest. He promised to bring economic growth, and that’s exactly what we have.
