摘要：Reacting to concerns that citizens from the European Union's 10 new
member countries could overwhelm their welfare systems, the established members
separately established rules to tighten migration or impose other restrictions
on the 10. The author says this strategy will hurt growth in the EU as a whole
without solving the welfare problem. He proposes that the EU adopt a common, and
generous, transitional quota for migration while reforming the welfare system to
ensure its future viability.
