Moreover, the sheer weight of their agricultural sectors and the backwardness of their infrastructure can force a reluctant EU to reform its inanely bloated farm and regional aid subsidies, notably the Common Agricultural Policy. That the EU cannot afford to treat the candidates to dollops of subventioary largesse as it does the likes of France, Spain, Portugal, and Greece is indisputable. But even a much-debated phase-in period of 10 years would burden the EU's budget - and the patience of its member states and denizens - to an acrimonious breaking point. The countries of central and eastern Europe are new consumption and investment markets. With a total of 300 million people (Russia counted), they equal the EU's population - though not its much larger purchasing clout. They are likely to while the next few decades on a steep growth curve, catching up with the West. Their proximity to the EU makes them ideal customers for its goods and services. They could provide the impetus for a renewed golden age of European economic expansion. Central and eastern Europe also provide a natural land nexus between west Europe and Asia and the Middle East. As China and India grow in economic and geopolitical importance, an enlarged Europe will find itself in the profitable role of an intermediary between east and west. The wide-ranging benefits to the EU of enlargement are clear, therefore. What do the candidate states stand to gain from their accession? The answer is: surprisingly little. All of them already enjoy, to varying degrees, unfettered, largely duty-free, access to the EU. To belong, a few - like Estonia - would have to dismantle a much admired edifice of economic liberalism. Most of them would have to erect barriers to trade and the free movement of labor and capital where none existed. All of them would be forced to encumber their fragile economies with tens of thousands of pages of prohibitively costly labor, intellectual property rights, financial, and environmental regulation. None stands to enjoy the same benefits as do the more veteran members - notably in agricultural and regional development funds. Joining the EU would deliver rude economic and political shocks to the candidate countries. A brutal and rather sudden introduction of competition in hitherto much-sheltered sectors of the economy, giving up recently hard-won sovereignty, shouldering the debilitating cost of the implementation of reams of guideline, statutes, laws, decrees, and directives, and being largely powerless to influence policy outcomes. Faced with such a predicament, some countries may even reconsider. Switching Empires By: Dr. Sam Vaknin Also published by United Press International (UPI)
