Once you make adjustments to your social spending, it takes times (it can take months) to get it to rise to the level of your funding.
You can see it rise by watching the %s in each catagory.
Its been said a few times now that DAR affects economy also,ive never seen it, but the devs have said it.So a low dar may cost you some small amount of possible income from your population.
Im one who bleeds the people til election time (like 2 months before),than i open the flood gates of "niceness" making everything free and removing taxes completely.
TIL i win the election,that its time to bleed them again.
You know, kinda like how politicians do it in real life
Lastly 20-25% percent is not bad in the game, as explained above,there are 3 or four parties,so 25% is circa an equal share.
And since you can push your dar from like 10% to 40% in a month or two,25% is not a bad place to start out at.
Things to help raise DAR:
1)increase social spending
2)lower domestic prices
3)research popular techs
And dont let a falling DAR at the beginnig of a scenario throw you,sometimes its just a result of the region going to its "mean" for the current settings, and not so much anything that youve done wrong.
IE-Its just making opening adjustments.
