This paper aims at courageously building the design of a conceptual system of thinking economics, conceived as an alternative to the routine one. In this purpose, methodologically, the paper is, pointing out several of our main conceptions that are developed in our researches, also several recent set of ideas and most recent works in the economic literature concerning the topic of productivity. Part of a larger research, our approach blame the common practice in economic life and, as well, in economics theoretical analyses concerning the conceiving and assessing productivity, as being almost exclusively quantitative and formal (ignoring important qualitative and causal aspects of the economic complex process). The organization and building of the paper is made in the logic of presenting the key concepts that are the pillars of the presented system of thinking, starting with the recent context of the New Long Crisis, with the requirements of the concept of knowledge society, with references to the European Union approaches, presenting our opinion concerning the value state and meaning, and finding them in the actual economic growth concept, which is presented as responsible for the entering in the New Long Crisis. Several roots from the genuine liberalism are invoked, in the more recent scientific environment of the service economy, which brought important new ideas and understandings concerning the general design of an economic activity (be it material or immaterial), the intellectual core of all human acts, the servicity approach, recovering the genuine conception on value and productivity. The debate results in pointing out several capital common misunderstandings which give occasion to (and even require) alternative approaches and conclusions, approaches which are conceived as (and can be) useful for developments in better directions that are solving problems on the very long time. The occasion is used also for reminding a most recent conception on an alternative economy.
