Canada may have the most skilled worker – oriented immigration system of all large countries. It uses a point system. 66% of foreign born persons have more than a high school degree. Australia, also with a point system, has 54%. the U.S. has 40%; Germany, 255: and Italy, 15%.
The United States’ system is so fragmented into dozens of entry points each with loopholes that is it hard to say how many of the roughly one million green cards awarded a year are for persons with strong work skills, but 20% or less might be a rough estimate.
A major problem with a formal skills-based system: the United States needs many workers without strong formal skills. They will be paid less. And, yes, they will need – like some 20 million American citizens who work at the bottom 25% of the wage scale – some forms of public assistance at some time.
