a society need the ability to adapt to ever changing threats, not just war and famine, a failed economy is a threat. we need governments that is capable to adjust themself to the current economic state, there is time where less regulated capitalism will lead to economic revival but make it to liberal to long and it will be blight hurting the economy. In periods strict control is needed to ensure the general population gets the necessity covered and the public infrastructure upgraded, this will require taxation, the difficult part is to not make said taxation to strict and last to long.
There is a need for a mixture of both financial models, and the flexibility to lean more into one and change when necessary. Sadly this is difficult due to the human nature prone to falling into ideological dogma.
