Sir Martin Wolf is absolutely right when in “Why immigration is hard to tackle”, November 2, when he says that “this is no area for stealth” and requests more transparency. For instance he makes a good point when mentioning that the “impact on the gross domestic product of migration should be measured after subtracting the incomes earned by the migrants” although perhaps there is also a need to differentiate between temporary and final migrants. Where I am not really sure is when he mentions market-compatible systems like auctions of work permits to be better than arbitrated point systems since neither one of them seems to be covering the problem that could be caused by in relative terms favouring the highest added value workers and therefore implicitly perhaps relegating your own to the lower earning sectors. Do you want to allow a foreigner to work as a maid so as to give your own professionals a better chance or do you want to give the foreign professionals a better chance and have your own work as maids? Not an easy proposition to handle.
Personally what I most favour, everywhere, is massive temporary worker programs so as to allow for the market to cover its short term needs without necessarily forcing the society to enter into long terms commitments. To make these temporary programs more feasible I am currently investigating the use of private insurance companies to guarantee compliance (going back home) instead of putting the burden on already overly stretched migration authorities.
The main obstacle to the development of temporary worker programs lies ironically in the arrogance of developed countries believing that anyone who gets there wants to stay there forever. So instead of making good livable room for all your temporary needs what you are getting is more and more permanent fixtures.
