Quote by Friedrich List
It is bad policy to regulate everything... where things may better regulate themselves and can be better promoted by private exertions but it is no less bad policy to let those things alone which can only be promoted by interfering social power.
Summary
This quote implies that while it is not advisable to excessively regulate aspects of society that can self-regulate or improve through private efforts, it is equally detrimental to neglect and not intervene in areas that require social intervention for progress. In other words, the quote suggests that finding the balance between too much regulation and lack of intervention is crucial in effective governance and promoting societal well-being.
