There are problems with the construction of social security hope to learn from Europe's high welfare hope that the higher the level of social security the better. European high welfare type social security system is bound to high taxes as a prerequisite, as Greece is the European state of this debt crisis trigger, it will be illustrated by Greece as an example. Greece's social security expenditures as a percentage of GDP were 16.47% in 1990, and have been on an upward trend since then, rising to 21.33% in 2007. Taxes as a share of GDP and social security expenditures as a share of GDP show a strikingly almost identical trend: in 1990, taxes as a share of GDP in Greece were 26.18%, and in 2007, they reached 32.33%. It can also be shown that higher social security spending leads to higher taxes.
