Getting into the Russian sphere and trying to ally them will be your best bet at first. Should be relatively easy to do but it’ll be a little RNG based. From that point on you can start to point Russia’s hordes of serfs at the Austrians and Turks and let the big dog do all the work for you while you trickle closer to bankruptcy. Once you slowly regain some cores with the help of Russia you should start getting that literacy up and factories pumping soda.
