That is the topic of my latest Bloomberg column, here is one bit:
A lot of the recent cross-border migration is planting a hugely positive, pro-trade legacy that will yield dividends for decades to come. The Chinese, Indians, Nigerians and many other groups around the world will continue to build economic connections, even when the countries involved aren’t always so geographically close. I expect the positive trade gains from these connections and personal networks will outweigh the downside from some higher tariffs in the meantime. Ultimately the opportunities are there, and the biggest problem is the lack of human talent to execute on them.
I do however see one big problem:
The internet shows some signs of breaking down into separate networks, connected only imperfectly. The Chinese “Great Firewall” has proved robust, and recently the European Union has moved toward creating its own set of stringent privacy and data protection laws, such as the new General Data Protection Regulation standards. Sitting here in Norway for a conference, I find I am unable to access many American websites, such as the Chicago Tribune, which are not (yet?) GDPR-compliant. There is thus a danger that the internet will become carved into three or more separate systems, to the detriment of trade, data flows and eventually personal connections.
Do read the whole thing.
