Amalie,
Looked at some of your countries. Here are some suggestions. Make sure you apply any changes to every country.
On the Automation page uncheck auto build new corps. The game will build corps based on shortages not profit.
Stop building corps in any country that has over 96% employment. The game needs some unemployed workers to move people between professions. In your main country you had new mining corps close because of worker shortages.
Move workers from the countries with lowest employment to the ones with the highest to get all your corps at 100% employment and country employment down to 96%.
Only build corps that make a good profit. At level 1 you don't have a lot of choices. Build as much mining as you can. Stay away from all Weapons, Ammo, Utilities and Govs except for the maintenance corps. There are a few Agri and Food corps that make an OK profit. Also a few of the level 1 Indies and Construction will make a decent profit.
You have a lot corps that are loosing 1B$ a monthh. Go to the Cash&Debt page and start closing the biggest losers and replace them with a profitable corp.
Lower your tax rate and increase profit transfer by the same amount. Your state corps will do about the same but your countries will be more likely to attract CEO HiTec corps.
