We think it was Art Laffer who said it best. Let's say the US invented a cure for cancer and China a cure for heart attacks. If China decided to ban the cure for cancer, should the US retaliate by banning the cure for heart attacks?

Obviously not! The US is better off trading with China regardless of what China does. And although things like computers and toys are not nearly as serious as a heart attack, the same principal applies. Think about this idea the next time you hear about some other country "killing" the US on trade.

The US has run a merchandise trade deficit every year since 1975. The US has also run persistent trade deficits with many countries around the world, including Canada and Germany for the past 40 years, China for 35 years, and Mexico for the past 20 years. And yet it's the US that remains a magnet for immigrants from around the world. If the US is getting killed economically, wouldn't people be leaving, not trying to get here? People vote with their feet and the votes clearly suggest there is more economic opportunity in America, enough more that people enter illegally.

Some are concerned that global trade flows for the US have peaked, and it is true that overall imports and exports slowed in late 2014, 2015 and 2016. But we attribute this to the large drop in oil prices. We spent less on oil imports and oil exporters (like OPEC) earned fewer dollars to spend back here.

But, "real" (inflation adjusted) US goods exports outside the oil sector rose 5% in 2016 and are up 2.6% per year in the last decade. The real value of non-oil imports increased 4.2% in 2016 and are up 2.5% per year in the past decade. All of these figures are outstripping real economic growth in the US. Trade is an unambiguous positive for growth worldwide.
