System dynamics is a discipline that studies how systems change over time and how their components interact, so we can find stable and unstable systems based on how they behave under equilibrium conditions and how they respond to external perturbations.
Stable systems are those that tend to return to a state of equilibrium after being disturbed by internal negative feedback forces, while unstable systems do not return to their equilibrium position, but disturbances provoke responses that amplify the change instead of counteracting it. , worsening the situation and possibly even collapsing.
Our pension system faces dangerous challenges that place it in the category of unstable and potentially explosive systems since it has been showing, for some time, worrying signs of unsustainability in the midst of demographic, economic and social changes, requiring a sustained and growing effort to prevent The explosive momentum of its instability will unleash disastrous consequences for future pensioners.
However, instead of making a structural and comprehensive change to the system to make it stable in the long term, due to the associated complexity and electoral risk, it was decided to make this effort through incremental changes in the parameters to keep it temporarily stable, alive, even if he is intubated and with assisted breathing, thus prolonging the agony.
The problem is that, although the political discourse sells us that the latest reform will be very long-lasting and definitive, since it is unstable and explosive, from time to time it will need new and more frequent parametric adjustments, which is why inventions such as the MEI or the solidarity quota, a euphemism not to call it a tax, will undergo upward changes in a few years to continue keeping the ship afloat, without prejudice to new adjustments in benefits, increases in the retirement age, up to 70 years as already seen in Europe and/or the minimum number of years of contributions. Quite a sudoku for future generations who intend to collect 100% of a dwindling public pension, made difficult by the high youth unemployment and precarious job market they face.
Thus, each new change is an addition and continues until the next and the most serious thing is that these are ingenious tax mechanisms disguised as contributions and solidarity but that will not translate into greater amounts of the pension, so each time, our The system is less contributory and distances the employer from our labor market, fearful and with incentives to accelerate the incorporation of new technologies that will reduce labor costs.
