Democracy is your problem. Democrats will hate you for dictatorial policies and will force you to mkae changes VERY slowly. I suggest you get rid of them and appoint some other party. Commies seem to not mind dictators and parties like royalists will love you if you do dictatorial stuff.
PS. If you wanna issue fast dictatorial policies, I recommend you play as Mauritania, N. Korea or China. There was also some Arab alliance thingy nation that also will love dictators, but its the smallest starting territory of the bunch.
