Serious people were appalled by Wednesday’s vote in the House of Representatives, where a huge bipartisan majority approved legislation, sponsored by Representative Sander Levin, that would potentially pave the way for sanctions against China over its currency policy. As a substantive matter, the bill was very mild; nonetheless, there were dire warnings of trade war and global economic disruption. Better, said respectable opinion, to pursue quiet diplomacy.

But serious people, who have been wrong about so many things since this crisis began  remember how budget deficits were going to lead to skyrocketing interest rates and soaring inflation?  are wrong on this issue, too. Diplomacy on China’s currency has gone nowhere, and will continue going nowhere unless backed by the threat of retaliation. The hype about trade war is unjustified  and, anyway, there are worse things than trade conflict. In a time of mass unemployment, made worse by China’s predatory currency policy, the possibility of a few new tariffs should be way down on our list of worries.

Let’s step back and look at the current state of the world.

Major advanced economies are still reeling from the effects of a burst housing bubble and the financial crisis that followed. Consumer spending is depressed, and firms see no point in expanding when they aren’t selling enough to use the capacity they have. The recession may be officially over, but unemployment is extremely high and shows no sign of returning to normal levels.

The situation is quite different, however, in emerging economies. These economies have weathered the economic storm, they are fighting inflation rather than deflation, and they offer abundant investment opportunities. Naturally, capital from wealthier but depressed nations is flowing in their direction. And emerging nations could and should play an important role in helping the world economy as a whole pull out of its slump.
