Whenever I play and avoid trying a UHV my economy is always the thing that collapses me. I've read strategy guides, I've even kept strictly to my historic and even avoided expanding to some of my possible areas as the romans. Is it because I use the civic mercantalism? My other stats only fair and usually settle around +10. Foreign is always my strongest stat because I like to take a lot of vassals and use the viceroy civic. It's really frustrating to keep having my empires collapse after building wonder after wonder and getting 2-3 golden ages per game I avoid the UHV.
What are specific things I can do to keep my economy high after I've stopped expanding?
