How to solve all the problems! ( not all but...)
As of 2000, for instance, a worker in Mexico earned a wage 40% that of a Mexican-born worker of similar education and experience working in America.
Most of this wage gap is down to productivity differences, stemming from disparities in the quality of infrastructure, institutions and skills. An individual worker, however talented, cannot hope to replicate the fertile environment of a rich economy all on his own. But transplanting a worker into rich soil can supercharge his productivity. A Mexican worker earns more in the United States than in Mexico because he can produce more, thanks to the quality of US technology and institutions........
In a recent report Sharun Mukand of the University of Warwick calculates the effect of movement by half of the developing world’s workforce to the rich world. Such a vast migration could never happen in practice, of course, but as a thought exercise it is instructive. If migration closes a quarter of the migrants’ productivity gap with the rich world, their average income would rise by $7,000. That would be enough to raise global output by 30%, or about $21 trillion. Other studies find even bigger effects. A 2007 paper by Paul Klein, now at Simon Fraser University, and Gustavo Ventura, now at Arizona State University, reckons that full labour mobility could raise global output by up to 122%. Such gains swamp the benefits of eliminating remaining barriers to trade, which amount to just 1.8-2.8% of GDP, reckons Mr Mukand.
PS This is so true, the temptation to try to stop immigrants from entering Europe is killing Europe. We need people to work and pay taxes and since there are no babies what we should do is open the doors to all that want to work and live here.
