Social democracy of some kind. Government involvement in certain industries such as healthcare, education, military, justice system, libraries, firemen, etc and certain regulations like on food, water, banking etc. So basically like most countries. The biggest problem with current American politics in my opinion is the rigid two party system which keeps anyone from rocking the boat.
The systems in place are limited in views. Or if you believe in a certain thing that puts you on one side or the other. Its not reasonable or logical, Im sick of it.
