Winderian,
I had a look at your main country, and I think I know why you are having money problems. You're indexes are off the charts.
270 Education, 220 Healthcare, 230 Transportation, 85% of LLW salary for Social Security.
I don't think the Education Index even increases graduate numbers, above 250.
The Transportation Index, only improves Welfare Index, and only upto 140 Transport Index.
Social Security, only improves Welfare Index, and only upto 80% of Low Level Workers Salaries.
Healthcare, is Simcountry's bottomless money pit, along with defense, there is basically no limit to how much someone can spend on it.
Anyone would be going broke, trying to maintain indexes that high.
