Suppose that by enacting a particular law we’d increase the U.S.Gross Domestic Product. But almost all that growth would go to the richest 1percent.

The rest of us could buy some products cheaper than before. But those gains would be offset by losses of jobs and wages.

This is pretty much what “free trade” has brought us over the last two decades.

I used to believe in trade agreements. That was before the wages of most Americans stagnated and a relative few at the top captured just about all the economic gains.

Recent trade agreements have been wins for big corporations and Wall Street, along with their executives and major shareholders. They get better access to foreign markets and billions of consumers.

They also get better protection for their intellectual property – patents, trademarks, and copyrights. And for their overseas factories, equipment, and financial assets.

But those deals haven’t been wins for most Americans.

The fact is, trade agreements are no longer really about trade. Worldwide tariffs are already low. Big American corporations no longer make many products in the United States for export abroad.

The biggest things big American corporations sell overseas are ideas, designs, franchises, brands, engineering solutions, instructions, and software.

Google, Apple, Uber, Facebook, Walmart, McDonalds, Microsoft, and Pfizer, for example, are making huge profits all over the world.

But those profits don’t depend on American labor — apart from a tiny group of managers, designers, and researchers in the U.S.

To the extent big American-based corporations any longer make stuff for export, they make most of it abroad and then export it from there, for sale all over the world — including for sale back here in the United States.
