By now, everyone knows the economy is booming under President Trump. But where and how it’s booming is even more important for both America's middle-class and the 2020 election.

Any incumbent president would be lucky to be able to campaign on my father’s economic record. Unemployment is hovering around a 50-year low. The stock market continues to set new highs. New, fairer trade deals with our closest trading partners, along with steady progress towards an equitable trade settlement with China, are securing a place for American workers in the global economy for decades to come.

General economic health is among the strongest predictors of electoral success for an incumbent president, and that’s especially true when the prosperity is shared across every level of society, the way it is in the Trump economy. As people here in Pennsylvania know all too well from previous experience, a “booming” economy isn’t worth much to ordinary folks if it doesn’t provide decent job opportunities and a chance to earn more money.

President Trump’s historic election victory in 2016 was fueled in large part by his promise to correct the uneven consequences of globalization and create a genuine, broad-based economic recovery after eight years of stagnation and misery under Barack Obama.

“Washington flourished, but the people did not share in its wealth,” my father said at his inauguration. “Politicians prospered, but the jobs left and the factories closed. The establishment protected itself, but not the citizens of our country.” When he promised to “make America wealthy again,” he was talking about uplifting the workers and entrepreneurs who are the backbone of our economy, not padding the bottom lines of wealthy investors to create the illusion of growth. Of course, Wall Street is thriving right along with the rest of the country, but that’s only because my father’s pro-growth policies have strengthened the fundamental elements of our economy to such a great extent.

The stock market is enjoying a record-setting run and our gross domestic product is growing at the healthiest clip in a decade, but President Trump’s America First agenda is achieving its core purpose: these gains are being enjoyed by Americans at every income level, and the greatest benefits are going to those on the lowest rungs of the socioeconomic ladder.

Low-wage earners are seeing their incomes grow about 50 percent faster than those at the other end of the spectrum. Everyone is winning, but workers in the bottom quartile are actually catching up to the nation’s highest earners, reversing the prevailing trend under Obama. Better yet, it’s a trend that keeps accelerating as the Trump presidency goes on.

That’s not because of government handouts or top-down federal regulations. It’s the natural result of historically low unemployment created by policies that unleash the power of economic freedom. American workers are in greater demand than they have been in decades, with more job openings than there are unemployed workers to fill them. Employers are raising entry-level pay and offering more robust benefits to compete for the limited supply of prospective employees, and the president’s trade and immigration policies have made it harder for companies to simply off-shore the work or resort to cheaper illegal immigrant labor.

A similar phenomenon can be observed geographically. The fastest personal income growth is taking place in the very parts of the country that were left behind during the mad rush of the ‘90s dotcom boom and the tepid “recovery” from the Great Recession under President Obama. Huge swaths of Western and Central Pennsylvania, for example, are no longer forgotten “rust belt” communities, but are rather becoming the thriving centers of industry that they once were years ago.

The voters in those communities are the ones who put Pennsylvania in Donald Trump’s column in 2016, and he’s delivered exactly what he promised them. The fact that this economic boom is primarily benefiting those voters bodes better for the President’s reelection than impersonal macroeconomic figures such as GDP growth.

Not all booms are created equal. Some booms are more equal than others, and the Trump boom is easily the most equal Americans have experienced in many decades. Americans at every income level are better off than they were three years ago, and there’s nothing any of the radical Democrats can say to obscure that fact.
