不好，社会负担压力大。。。

请问社会负担要如何理解呢？ 怎样的一个比例会比较合适？

这个，我不是这方面的研究。。。。财政学。。。

好吧，还是谢谢...

Let's figure it out step by step.

Government pensions spending, including both pensions for government employees and government pensions for workers, like Social Security, started out at the beginning of the 20th century at zero percent of Gross Domestic Product (GDP).

It increased very slowly during the first half of the century. It was only in 1931 that government pension expenditure reached 0.12 percent of GDP.

Pension expenditure breached 5 percent of GDP in 1980. Pensions expenditure is expected to reach 6.7 percent of GDP in 2015.

Normally speaking, government needs to create more value($) for the social well being. Thus, the more amortized in pension costs, the less will be available for this objective.  However, if the expenditure is low, then the stability will be sacrificed.  

The modern pension administration was originated after WWII, I don't believe there is a proved "best" ratio for this criteria.   

Let's keep one eye on it.  :)
Thank you.
