Different ways you can raise or maintain a decent DAR. You can raise social spendings and/or lower taxes. Also keeping up with demand in Timber, Agri, Water, Power, Petro and Consumer Goods will help your DAR as well as maintaing an affordable domestic price for those as well. You dont have to max out social spendings to keep a decent DAR or one that will you elections. I usually keep my at the recommended levels, except in Infrastructure and Education. I keep taxes at sane levels, not too much or too little.
