Social security% (Little Upsilon)

What is the best target for social security %?
i see some players had set 10% and some others 40% or 90%, mine is 82%.

Depends

If you are trying to get a high country score you want high soc sec.

Rebellions occur more frequently if your welfare index is low. Soc Sec is one variable in the welfare index.

If your unemployment is low and you do not have very many old people soc sec is not very expensive. If you are going through a population bust or you have massive unemployment soc sec can be very painful.
