Close: solutions will most often be derived from the real world (trial and error), and real economics, which says that capitalism is the best system, albeit an imperfect one, and therefore needs some tweaking now and then. How much and what tweaking is of course a matter of ongoing debate between reasonable people, and probably depends a lot on what various communities and peoples prefer. I.e. most people in Sweden are happy with a more collectivist version of capitalism, most people in the US are happier with another sort of system, and so on.
