OK, I took a look and here we go:
1. Your doing OK on Education, Health and Transportation in general. However, you need to get your Elemantary Schools in line with the Highschools and Universities. They all need to have the same index. Right now it's 108,124 and 126. This means that your Elemantary Schools are dragging down your educational index by almost 20 points. In general aim for 200 education (all three indexes), 150-180 transportation (all three indexes) and 150+ health. This is a slow and gradual process. Don't do it overnight, or you will have worker shortages and money deficits. Raise it by 5-10 points every day or so. Education must always have the priority (everything else starts from there).
2. Your biggest problem right now is that you have too many corps for your population. You need to close at least 6-7 corps. Close down all those food corps with 10% hiring. The target set for corps at the "important things to do" page is misleading. Never build a corp that you don't ALREADY have all the workers for. Never build a corps if even one of your existing corps has a worker shortage. After your close the corps the rest will go to 100% production, and so your business index will rise sharply and so will your welfare index and this means your remaining corps will produce more and make more money ;)
3. Your consumption quality index is too high (225). This practically means that you buy too expensive quality supplies for your population, which doesn't pay off in welfare or anything else. To stop wasting money go to Trade>Order Strategy and Quality and set all qualities at 120 for now. This will save you money right now without hurting you in any way for now. Later on, you will know if/what to change in this...
4. You have a HUGE defensive cost of 5.2B per month. This will surely kill your country when the beginner booster money stops in a month or so. You have a single country in secured mode, so you really don't need any army at all. None can attack you anyway. Unless you want to raid C3 countries (not a bad idea for later), deactivate or better sell AT ONCE all your weapons and ammo, at least the defensive ones which are useless for raiding anyway. Because right now they're just standing there costing you money. One side profit will be that over 240.000 workers will return from your useless army to your factories and man them ;) You can start thinking about having an army when your country is over 35 million people and you have 15-20T in hand. Until then think of your indexes and your economy. None can attack you anyway!
5. Finally, set your government salaries around 225 and your industry salaries around 300. Lower your taxes and raise the profit contributions (10% and 85% are fine). This way you won't lose any income, but will also attract some CEO invetment in your country, which is a very good thing. You need private corps because you will get more people to work this way (housewifes and hadicapped if you set up back to work schools and special clinics at the expense of Univeristies and Hospitals respectively). But private corps will only come if you lower your taxes and raise your welfare level (it's 111 now, you should aim at least for 120-125). After you do so, advertise in the forums so that CEOs will know and come.
These are some basic stuff. The rest you will find out on your own as you go...
