Where I come from, “the economy” isn’t just about lines on a graph or numbers on a screen. It’s about how much money people have in their pockets and how much their groceries cost. It’s about how many shops are shuttered on their high street and whether they can afford to make the rent.

In Pennsylvania, when voters go to the polls next week, the economy will be weighing very heavily on their minds. Our state will probably decide who becomes the next president of the US, and how we vote will also be a test of Joe Biden’s policies. The economy is one of the top issues for voters in our state. Many of them will be asking: am I in a better place now, compared with where I was four years ago?

I come from a family of steelworkers near Pittsburgh. My father was a steelworker in the city, and so is my son. I’m also a rep for United Steelworkers, one of the largest unions in our country. As you can imagine, the most important issue in town right now is the steel deal. The Japanese steelmaker Nippon has been trying to buy US Steel for the past year, and though the company has promised to honour US Steel’s agreement with our union, we have many reasons to be doubtful.

Not only is steel integral to our national security, raising questions about foreign takeovers, but there’s nothing to stop the company from cutting union jobs a few years down the line. The CEO of US Steel stands to walk away with $70m (£54m) if the deal completes. It’s the same pattern that repeats again and again: the money stays at the top, while people at the bottom are forgotten about.

I’m glad that Kamala Harris has committed to blocking the sale. And I’m glad that the Biden administration has questioned the value of takeovers like these. Look at the Chips Act, or the Inflation Reduction Act: both were about spurring investment in our economy and building up productive capacity in the US.

For too long, globalisation has meant a race to the bottom, with firms outsourcing labour and offshoring production to the places where it’s cheapest. Most employees have been working harder but getting paid less: from 1973 to 2013, the hourly wage for a typical worker rose just 9%, while productivity increased by 74%. No wonder so many people are exhausted and struggling to keep their heads above water.

Here’s the thing: Donald Trump says he gets it, but he doesn’t. He talks about inflation killing our country under Biden, but he never says that record corporate profits are one of the drivers of inflation. He talks about the housing crisis, but then he blames the lack of affordable housing on immigrants. He is a master at spinning simple answers to complex problems, but he has no real solutions.

I think most people are smarter than Trump gives them credit for. Most people have a sense that the reason daily life has become so expensive isn’t just because of the war in Ukraine or supply-chain bottlenecks. It’s because corporations got greedy, and started using inflation as cover to raise prices. If I can sell you a cup of water for $10, why would I drop the price to $7? The Democrat Pennsylvania senator Bob Casey has been campaigning explicitly on “greedflation”.

It feels as though the message is cutting through, but I know plenty of steelworkers will still vote Trump, though almost all the unions have backed Harris. Where I live is rust belt territory. It’s a place that once boomed on coal, steel and cars. It’s a place that struggled to reinvent itself after the decline of the manufacturing industries, and lost a lot of jobs.

Since the pandemic, we’ve been suffering. I live in Washington, a town south of Pittsburgh, where I’m also the local mayor. I’ve seen how the shift towards working from home has damaged some of our small businesses, and how our healthcare workers suffered from Covid-19.

But I can also see the positives that “Bidenomics” has brought to our community, and I’m hoping these will cut through. One of the biggest complaints I hear now from residents is: “Why is there so much construction? We can’t cross the road!” Thanks to a huge boost in federal spending, with the Inflation Reduction Act earmarking billions of dollars to support infrastructure projects, there are many more cranes than there used to be.

I always say, that’s infrastructure money working for us. When the Fern Hollow bridge collapsed in Pittsburgh, it was rebuilt in record time. Pennsylvania is particularly well placed to benefit from federal investment because it’s the second largest producer of energy in the US after Texas, and we need that climate spending if we’re going to transition to a clean energy economy. I’m just hoping that other voters feel the same way.
