In order to make some non-growing system profitable, what would we do?
First, I would not be engaged in the artificial growth of the system, or growth due to other technologies, since the growth of these same technologies will be insignificant in significant percentages for the economy as a whole, and therefore not significant and not effective.
Secondly, I would not be involved in mergers and acquisitions, since they are not dealt with, they either happen, or it is better not to do this.
Third, there is nothing more important than the revision of the parts and workers of the business itself, the opportunities for optimization by combining duplicating functions. It will never be that everything that is possible has been done, there are always opportunities for optimization, including in joint efforts with market partners.
In total, we come to the conclusion that any business on planet earth must be compared with growing green plants and trees, since the process of growth in the same environment has similar signs and capabilities.
