European countries have to reduce their budgetary deficit to 3 % of their GNP if they want to join to the Euro. France has attempted to reach the 3 % goal by increasing taxes. The consequence of this policy is that slower economic growth with a slower economy fiscal receipts will be insufficient for the 3 % objective to be reached in the future. If it is not, according to the stability pact, penalties will have to be paid. Which would probably lead to further tax increases.
