If something like this could be added at this point in development, I think it would be nice when you click to view the details of a situation (where you see the causes and effects) to also get suggestions, perhaps by your ministers, on what policies you could implement to deal with the situation. I know that after many playthroughs you eventually learn what policies affect each situation anyway, but it would add some more realism I think.
It could something like: Your minister of Finances, John Minister, recommends that you implement Public Tax Returns in order to deal with the ongoing Tax Evasion in the country.
